EXECUTIVE SUMMARY
The technical knowledge that NZ needs to recover — the Recovery Library itself, surgical procedure guides, pharmaceutical references, agricultural databases, engineering manuals, navigation tables — exists overwhelmingly as digital files. If those files become unreadable before the knowledge is transferred to durable media, the knowledge is lost, and NZ’s recovery capacity contracts accordingly. New Zealand’s digital knowledge stores — servers, hard drives, SSDs, laptops, tablets, phones, and cloud-cached local copies — collectively hold more useful technical information than could be printed in a century of continuous operation. The question is not whether NZ has enough knowledge stored digitally. The question is how much of that knowledge can be transferred to print before the hardware that stores it becomes unreadable.
Electronics fail. Hard drives have a median lifespan of 3–6 years under continuous use; SSDs degrade after roughly 5–10 years depending on write cycles and storage conditions; server hardware depends on fans, power supplies, and controller boards that cannot be replaced without imports.1 Under the baseline scenario (grid continues, buildings are climate-controlled), NZ’s digital infrastructure degrades gradually over years, not suddenly. But degradation is cumulative and accelerating — every year, more drives fail, more screens crack, more controller boards develop irreparable faults. By Year 10–15 (Phase 4–5), the majority of NZ’s pre-war digital storage will be unreadable.2
Meanwhile, NZ’s printing capacity is substantial but finite and declining. Laser printers and copiers depend on toner cartridges, photoconductor drums, and fuser assemblies — all imported, all irreplaceable (Doc #5). The manual printing methods that replace them (Doc #29, Doc #31) produce output at roughly 1–5% of laser printer speed. There is a window — approximately Phase 1 through early Phase 3 (Years 0–5) — during which NZ has both functional digital storage to read from and functional printing capacity to write to paper. This window closes from both ends simultaneously.
This document provides the priority schedule for what digital knowledge to print, in what order, at what volume, in what format, and how to coordinate the effort across NZ’s distributed printing infrastructure. It is the bridge between the digital era and the print era — the schedule that determines what knowledge NZ carries forward and what it loses.
Key honest uncertainty: The rate at which NZ’s electronics degrade depends on maintenance conditions, environmental factors, usage patterns, and the specific hardware mix — none of which can be precisely predicted. The timelines in this document are estimates based on general hardware reliability data, not NZ-specific inventories. The national skills census (Doc #8) and a hardware condition survey would significantly narrow these estimates.

RECOMMENDED ACTIONS (BY ACTUAL URGENCY)
Phase 1 (Months 0–12) — The Laser Printing Window
[Weeks 1–4] Establish digital content extraction teams. Identify personnel with IT skills (librarians, systems administrators, database managers) and assign them to content curation — identifying, formatting, and queuing digital files for print. This is primarily a workforce allocation decision, though technical challenges exist — particularly accessing DRM-locked institutional databases, converting proprietary file formats to printable output, and establishing access credentials for institutional servers whose administrators may be unavailable. (Moderate urgency — printing hardware is functional and toner is not yet scarce, but the prioritisation framework must be in place before large-scale printing begins.)
[Weeks 2–8] Print the entire Recovery Library at maximum volume. The Recovery Library itself (estimated 25,000–35,000 pages across all documents) is the single highest-priority printing job.3 Target: 200–500 complete sets distributed to regional centres, hospitals, libraries, and marae across NZ. This is already covered by Doc #5 and Doc #30 — listed here because it is the first and most important item on the digital-to-print schedule.
[Months 1–6] Begin Priority Band 1 extraction (Section 4): medical references, pharmaceutical data, and surgical procedure guides. These are time-critical because healthcare decisions made with incorrect or missing information have immediate consequences, and the medical professionals who currently supplement their memory with digital lookups will lose that capability as devices fail.
[Months 3–12] Begin Priority Band 2 extraction (Section 4): agricultural guides, seed databases, veterinary references, and food preservation data. These are seasonally time-critical — agricultural decisions depend on having information available before planting seasons.
[Months 6–12] Conduct hardware condition survey as part of the national skills census (Doc #8). Inventory: server rooms, NAS devices, institutional hard drive arrays, and major digital collections (universities, Crown Research Institutes, LINZ, NIWA, GNS Science, public libraries). Estimate remaining operational life. Prioritise extraction from hardware showing early signs of degradation.
Phase 2 (Years 1–3) — Peak Extraction Period
[Years 1–2] Print Priority Bands 3–4 (Section 4): engineering data, manufacturing references, navigation tables, and maps. These become critical as NZ’s industrial self-sufficiency programme expands and maritime trade develops.
[Years 1–2] Prioritise internationally valuable content during the AI facility’s operational window. If the AI inference facility (Doc #129) remains operational, it could accelerate the digital-to-print programme in two ways. First, AI-assisted curation and formatting — identifying, summarising, and formatting digital content for print — could reduce the person-hours required per page of output. Second, and potentially more significant, the AI facility could produce content that does not yet exist in any digital archive: region-adapted recovery documentation for Australia, the Pacific Islands, and South America; translations of critical technical material into Spanish, Portuguese, Samoan, and other languages; and synthesised reference guides compiled from multiple digital sources. This generated content should be printed during the same window as extracted content, because it has trade and diplomatic value that could be as high as any physical export NZ puts on a vessel (Doc #129, Doc #151).
[Years 1–3] Transition extraction workflow to manual printing as toner stocks deplete. Digital files continue to be readable (screens, laptops) but output shifts to handwritten transcription, stencil duplication, and screen printing of key diagrams. Performance gap: Manual methods produce roughly 1–5% of laser printer throughput (Section 2.1), so only the highest-priority remaining content can be extracted during this phase. The transition also increases labour requirements per page substantially — a laser printer produces a page in seconds with minimal operator involvement, while handwritten transcription of a dense reference page may take 30–60 minutes, and stencil or screen printing requires setup time per page that only amortises at moderate run lengths (Doc #31). The binding constraint shifts from toner to person-hours.
[Year 2–3] Begin systematic backup of digital files to the most durable available media. Where printing is not feasible for large datasets (e.g., topographic databases, complete meteorological archives), copy files to the longest-lived storage media available — write-once optical discs (M-DISC or standard DVD-R stored cool and dry) and multiple redundant hard drives stored unpowered in controlled environments.4
Phase 3 (Years 3–7) — Closing Window
[Years 3–5] Extract remaining Priority Band 5 content (Section 4): educational curricula, technical training materials, historical and cultural archives. By this phase, toner printing is largely exhausted. Extraction means either manual transcription from screens or selective printing on domestically produced paper with domestically produced ink (Doc #29).
[Years 5–7] Final hardware triage. Identify the last functional digital storage devices. Concentrate remaining extraction effort on irreplaceable content — unique datasets, NZ-specific research, institutional records — that exists only in digital form.
ECONOMIC JUSTIFICATION
Person-years of labour
The digital-to-print programme is primarily a labour cost, not a materials cost. The materials (paper, toner) are already allocated through the printing supply strategy (Doc #5). The additional cost is the human effort to curate, format, and manage the extraction.
Content curation and formatting teams:
- Phase 1: 20–50 people full-time (librarians, IT staff, subject-matter experts reviewing content for accuracy and priority). Approximately 20–50 person-years.
- Phase 2: 30–80 people as the programme scales and manual methods require more labour per page. Approximately 60–240 person-years over 2 years.
- Phase 3: 10–30 people for final extraction. Approximately 30–120 person-years over 4 years.
Total estimated labour: 110–410 person-years over 7 years, with the majority concentrated in Phase 2.
The labour cost is front-loaded with scarce specialists: Phase 1 requires librarians, IT staff, and subject-matter experts who can curate and prioritise digital content — skills that are in limited supply and cannot be quickly trained. As the programme progresses into Phases 2–3, the work shifts increasingly toward manual transcription, binding, and distribution — general labour that can be drawn from a large available workforce.
What this produces
- Physical copies of the most important 5–15% of NZ’s accessible digital knowledge, preserved indefinitely on paper
- An estimated 10–50 million printed pages of reference material across all priority bands (the range depends on toner availability, workforce allocation, and how aggressively the programme is prioritised)
- Distributed knowledge that survives complete electronics failure — readable by anyone with eyes and light, requiring no power, no spare parts, no technical skill to access
Cost of not doing this
Without systematic digital-to-print extraction:
- NZ’s knowledge base contracts to whatever was already in print before the event, plus whatever the Recovery Library covers
- Pre-event NZ print holdings are substantial (public libraries hold approximately 8–12 million physical volumes nationally, university libraries hold millions more), but these collections are heavily skewed toward fiction, general non-fiction, and outdated editions.5 The technical depth NZ needs — current pharmaceutical formularies, surgical atlases, engineering handbooks, agricultural research, materials science data — exists overwhelmingly in digital form
- Medical professionals lose access to drug interaction databases, dosing calculators, and diagnostic references that they consult daily on digital devices
- Engineers lose access to materials specifications, structural calculations, and manufacturing data
- Once the hardware storing that knowledge fails, the data is unrecoverable — there is no mechanism to regenerate it from other sources
The comparison: 110–410 person-years over 7 years to preserve the most critical fraction of NZ’s digital knowledge is a modest investment relative to the cost of losing that knowledge entirely. For context, NZ’s pre-war library and archives workforce was approximately 5,000–8,000 people.6 Redirecting 1–5% of that workforce to digital extraction is a minor reallocation.
1. THE DEGRADATION TIMELINE
1.1 What NZ has stored digitally
NZ’s digital knowledge exists across several infrastructure layers, each with different failure characteristics:
Institutional servers and data centres:
- Universities (8 universities, each with terabytes of research data, digital library subscriptions, and institutional repositories)
- Crown Research Institutes (NIWA, GNS Science, Scion, AgResearch, Plant & Food Research, ESR, Manaaki Whenua — collectively holding NZ’s most important scientific datasets)
- Government agencies (LINZ topographic data, Stats NZ census data, MPI agricultural data, MBIE standards and regulations)
- District Health Boards / Te Whatu Ora (patient records, clinical guidelines, pharmaceutical databases)
- National Library / Alexander Turnbull Library (digitised collections, NZ heritage materials)
- Public library systems (catalogue data, e-book licences — the licences are worthless without internet, but locally cached content may exist)
Personal and institutional computers:
- An estimated 2–3 million laptops and desktops in NZ households, businesses, and institutions7
- Each contains some quantity of locally stored documents, downloaded references, cached web pages, and software
- The aggregate is enormous but fragmented, poorly organised, and mostly inaccessible to systematic extraction
Portable storage:
- USB drives, external hard drives, SD cards — widely distributed, individually small, collectively significant
- These are the most portable and most easily damaged storage media
1.2 How electronics fail
The failure modes are well understood:8
| Component | Failure mode | Typical lifespan | NZ-specific notes |
|---|---|---|---|
| Spinning hard drives (HDD) | Mechanical: bearing wear, head crash, spindle motor failure | 3–6 years continuous use; longer if stored unpowered | NZ’s humid climate (especially North Island) accelerates corrosion of internal components in uncontrolled environments |
| Solid-state drives (SSD) | Charge leakage in NAND cells; controller failure | 5–10 years active; stored data degrades over 1–5 years unpowered depending on temperature | Higher temperatures accelerate charge loss; NZ’s temperate climate is relatively favourable |
| Server power supplies | Capacitor ageing (electrolytic capacitors dry out) | 5–10 years | Replaceable between identical models; no domestic production |
| Fans (servers, desktops) | Bearing wear, dust accumulation | 3–7 years | Failure causes thermal shutdown; can sometimes be replaced with scavenged units |
| LCD/LED screens | Backlight failure, driver board failure, capacitor ageing | 5–15 years | Screen failure does not destroy the stored data — the drive can be removed and read on another machine |
| Laptop batteries | Capacity degradation, cell failure | 2–5 years to unusable | Laptops can operate on mains power without batteries |
| Network switches/routers | Power supply failure, capacitor ageing | 5–15 years | Needed only for networked access; standalone machines work without network |
The aggregate picture: NZ’s digital storage does not fail on a single date. It decays along a curve. Assuming a mixed-age fleet of hardware at the time of the event, roughly:
- Year 0–3: 10–25% of devices fail (those already old or marginal at the event)
- Year 3–7: An additional 25–40% fail (mid-life hardware reaching end of life)
- Year 7–15: An additional 20–30% fail (the newest and most robust hardware)
- Year 15+: Scattered survivors — a few robust machines, some solid-state media, optical discs
These figures are estimates based on general reliability engineering data.9 The actual curve depends on the age distribution and maintenance state of NZ’s hardware fleet, which the skills census (Doc #8) would establish.
1.3 What accelerates failure
- Power fluctuations: Grid instability (voltage spikes, brownouts) damages electronics. NZ’s grid is expected to remain stable under the baseline scenario (Doc #67), but localised fluctuations are possible, especially as grid maintenance personnel are stretched thin.
- Humidity and temperature: Uncontrolled environments — warehouses, garages, unheated buildings — accelerate corrosion and capacitor degradation. NZ’s North Island humidity is a particular risk.
- Physical damage: Devices dropped, water-damaged, or cannibalised for parts.
- Use without maintenance: Servers running continuously without cleaning (dust accumulation) or fan replacement.
1.4 What slows failure
- Climate-controlled storage: Keeping critical servers and storage devices in stable, dry, cool (18–22 degrees C) environments extends life significantly.
- Power conditioning: UPS units and voltage regulators protect against grid fluctuations. Existing UPS batteries will fail within 2–5 years, but the voltage regulation circuitry remains functional on mains power.
- Reduced duty cycles: Devices powered on only when needed, rather than running continuously, extend mechanical and thermal life. This is especially important for spinning hard drives.
- Cannibalisation: Scavenging working components (power supplies, fans, drives) from failed machines to keep others running. This extends the fleet’s functional life but accelerates the rate of total loss as the donor pool shrinks.
2. PRINTING CAPACITY VS. TIMELINE
2.1 The printing capacity curve
NZ’s printing capacity follows its own decline curve, driven by consumable depletion:
Phase 1 (Months 0–12): Peak capacity
- NZ’s installed fleet of 30,000–60,000 commercial MFCs and 200,000–500,000 desktop laser printers (Doc #5) provides enormous throughput
- At even modest utilisation (5% of fleet active), output capacity is millions of pages per day
- Constraint: toner supply, not hardware. National toner stocks estimated at 80,000–350,000 cartridges (Doc #5)
- With print optimization (Doc #30), estimated total production capacity: 800 million to 5+ billion pages from existing stocks
Phase 2 (Years 1–3): Declining capacity
- Toner stocks depleting. Printer hardware beginning to fail (drums, fusers, pickup rollers)
- Fleet consolidation: concentrate remaining toner and functional printers at regional production centres
- Output declines from millions to tens of thousands of pages per day nationally
- Manual printing methods (stencil duplication, screen printing) beginning to supplement
Phase 3 (Years 3–7): Transition to manual
- Toner largely or fully exhausted at most sites
- Manual printing methods (Doc #29, Doc #31) producing hundreds to low thousands of pages per day nationally
- Digital-to-print extraction shifts from laser printing to manual transcription and screen printing
Phase 4+ (Years 7–15): Manual era
- Printing capacity fully domestic — paper from Kinleith mill or smaller regional pulp operations (Doc #29), ink from linseed oil (requires flax seed cultivation, oil pressing, and heat-bodying to achieve suitable viscosity) and lamp black (requires controlled incomplete combustion of resinous wood or oil — Doc #29 details the full ink production chain), printing by letterpress, screen, and stencil (Doc #31)
- Digital sources increasingly unavailable — extraction becomes a salvage operation from surviving hardware
2.2 The window
The overlap between “digital sources readable” and “printing capacity available” defines the extraction window.
Year: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Digital: ████████████████████████████████████████████████░░░░░░░░░░░░░░
Laser: ████████████████████████░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
Manual: ░░░░░░░░░░░░████████████████████████████████████████████████████
Overlap: ████████████████████████████████████████████████░░░░░░░░░░░░░░
PEAK EXTRACTION WINDOW
(█ = high capacity; ░ = low or declining capacity)
The peak extraction window is approximately Years 0–5. During this period, both digital storage and laser printing are broadly functional. After Year 5, laser printing is largely gone and manual methods cannot match the extraction rate. After Year 10–12, digital storage itself is failing at scale.
Critical implication: Content that is not printed or otherwise transferred to durable media by approximately Year 5–7 has a high probability of being permanently lost. Every month of delay in beginning systematic extraction narrows the window.
3. FORMAT OPTIMIZATION FOR LONGEVITY
3.1 Paper longevity
Paper is a proven archival medium. Books printed 500 years ago remain readable. Modern acid-free paper, stored in controlled conditions, has a life expectancy measured in centuries.10 Even standard office paper stored indoors lasts decades.
For maximum longevity of printed extraction output:
- Use acid-free paper where available (most modern office paper manufactured in NZ and Australia is acid-free or low-acid; verify stock with major NZ distributors such as OfficeMax/Winc and Paper Plus)
- Store printed materials in dry, cool, dark environments (away from direct sunlight, which degrades paper and fades toner) — NZ’s South Island inland locations offer naturally favourable conditions; North Island coastal sites require dehumidification
- Bind documents to prevent page loss and physical damage (Doc #30, Section 6)
- Laminate critical single-sheet references (Doc #30, Section 7)
3.2 Page density and legibility trade-offs
The digital-to-print programme faces a fundamental tension: denser pages preserve more information per sheet (conserving scarce toner and paper) but become harder to read, harder to photocopy, and more likely to require reprinting due to errors.
Recommended density by content type:
| Content type | Font | Size | Columns | Margins | Est. chars/page | Notes |
|---|---|---|---|---|---|---|
| Prose text (medical guides, procedures) | Garamond | 10.5 pt | 1 | Standard (Doc #30) | 3,000–3,500 | Readability paramount |
| Reference tables (drug dosing, materials data) | Garamond/Calibri | 8–9 pt | 1–2 | Reduced | 4,500–6,000 | Lookup use; smaller type acceptable |
| Navigation/engineering tables | Calibri | 8 pt | 2–3 | Minimum | 6,000–8,000 | Numeric precision required; clear column separation |
| Maps and diagrams | N/A | N/A | N/A | Minimum | N/A | Print at maximum resolution on best available paper |
| Index/catalogue pages | Garamond | 8 pt | 2–3 | Reduced | 5,000–7,000 | Scanning/lookup; dense is acceptable |
Two-column layout is strongly recommended for reference material. It increases content per page by an estimated 10–20% compared to single-column at the same font size (the range depends on line spacing, hyphenation frequency, and column gutter width — wider gutters reduce the gain). Two-column layout is also more readable for reference lookups than single-column, because the eye traverses shorter lines (45–75 characters per line, which is within the optimal range for reading comprehension).11
3.3 Illustrations and diagrams
Medical diagrams, anatomical illustrations, engineering schematics, botanical identification images, and maps are among the highest-value content for printing — and the most toner-intensive. A single full-page anatomical diagram may consume as much toner as 5–15 pages of text, depending on tonal density and coverage area.12
Guidelines:
- Print diagrams at the minimum size that preserves usability. A surgical illustration that works at A5 should be printed at A5, not full A4.
- Convert colour diagrams to high-contrast greyscale where colour does not convey essential information.
- Reserve colour printing for content where colour is diagnostic: tissue identification, mineral identification, wiring colour codes, map elevation coding.
- For maps: print at the largest feasible scale on the largest available paper (A3 where possible). Maps lose critical information at reduced scale.
- For botanical/zoological identification: colour reproduction matters for distinguishing edible from toxic species. These are among the few categories where colour toner expenditure is justified.
3.4 Redundancy and distribution
A single copy of any printed document is a single point of failure. The extraction programme must produce multiple copies distributed geographically.
Minimum distribution targets:
| Priority Band | Copies per document | Distribution |
|---|---|---|
| Band 1 (Medical) | 50–200 | Every hospital, major medical centre, and regional civil defence hub |
| Band 2 (Agricultural) | 30–100 | Every regional council, agricultural extension office, and major farming community |
| Band 3 (Engineering) | 20–50 | Major workshops, factories, power stations, and technical training centres |
| Band 4 (Navigation/Maps) | 30–100 | Ports, coast guard stations, regional centres, and maritime training facilities |
| Band 5 (Educational/Cultural) | 10–30 | Regional libraries and educational institutions |
These targets are aspirational and depend on toner availability. The priority schedule (Section 4) is designed so that if toner runs out earlier than expected, the most critical content has already been printed.
4. PRIORITY BANDS
4.1 Prioritisation principles
The ordering reflects three factors:
Consequence of loss: What happens if this knowledge is unavailable? Medical knowledge loss causes preventable deaths. Agricultural knowledge loss causes food production failures. Historical knowledge loss is regrettable but not immediately dangerous.
Availability in existing print: Knowledge already widely available in NZ libraries and bookshops in physical form is lower priority for extraction than knowledge that exists only or primarily in digital form.
Shelf life of relevance: Knowledge needed immediately (Phase 1–2) is higher priority than knowledge needed in Phase 5–6, because the extraction window may not last that long.
4.2 Band 1 — Medical and Pharmaceutical (Print immediately)
Estimated volume: 500,000–1,500,000 pages across all items and copies
| Content | Source | Est. pages (master) | Rationale |
|---|---|---|---|
| New Zealand Formulary (complete) | NZ Formulary online database | 3,000–5,000 | Drug dosing, interactions, contraindications — consulted daily by every prescribing clinician. Exists primarily in digital form.13 |
| Surgical procedure atlas (major procedures) | Digital surgical references, institutional subscriptions | 5,000–10,000 | Illustrated guides for procedures that NZ surgeons will need to perform without specialist referral. See Doc #20. |
| Emergency medicine handbook | Best Practice Advocacy Centre (bpacNZ), Starship clinical guidelines | 1,000–2,000 | Paediatric and adult emergency protocols. |
| Infectious disease management | ESR surveillance data, WHO guidelines (cached) | 1,000–2,000 | Antibiotic selection, infection control, outbreak management. |
| Diagnostic imaging interpretation guide | Institutional radiology teaching files | 2,000–4,000 | While imaging equipment functions, interpretation skill must persist. |
| Dental procedure manual | NZ dental school curricula | 500–1,000 | Dental care without referral to specialists. |
| Mental health and psychiatric medication guide | NZ Formulary, Te Whatu Ora clinical guidelines | 500–1,000 | Psychiatric medication tapering protocols are critical as stocks deplete (Doc #122). |
| Veterinary formulary and procedures | MPI resources, Massey veterinary school | 2,000–4,000 | Livestock health management (Doc #124, Doc #122). |
| Midwifery and obstetric reference | NZ College of Midwives guidelines | 500–1,000 | Maternal and neonatal care without hospital infrastructure. |
Why Band 1 is urgent: Medical professionals currently rely on digital point-of-care references for dosing, drug interactions, and procedural guidance. These are not memorised — they are looked up. When the lookup device fails, the clinician is working from memory, which is unreliable for the precision required in pharmaceutical dosing. Printing the NZ Formulary in the first months — while toner is abundant and printers are functional — is one of the highest-value uses of the laser printing window.
Existing print gap: NZ hospitals do maintain some printed references (the British National Formulary and its NZ supplement have been printed historically), but the trend over the past decade has been toward digital-only access. Many clinical guidelines, interaction databases, and procedural references exist only in digital form or in outdated print editions.14
4.3 Band 2 — Agricultural and Food Production (Print in first year)
Estimated volume: 300,000–800,000 pages
| Content | Source | Est. pages (master) | Rationale |
|---|---|---|---|
| Crop production guides (all NZ-viable crops) | Plant & Food Research, FAR, MPI | 2,000–4,000 | Planting, cultivation, harvest, pest management for every crop NZ can grow under nuclear winter (Doc #77). |
| Seed identification and saving guide | Heritage seed networks, Koanga Gardens data, agronomy texts | 1,000–2,000 | Essential for Doc #77 (seed preservation). |
| Pest and disease identification (crops and livestock) | MPI biosecurity resources, AgResearch | 2,000–4,000 | Identification guides with images — pest management without imported chemicals. |
| Soil management and composting | Manaaki Whenua — Landcare Research, regional council data | 1,000–2,000 | Fertility management without imported fertiliser. |
| Food preservation methods | NZ food science literature, FAO references | 500–1,000 | Smoking, salting, drying, fermentation, canning procedures (Doc #78). |
| Fisheries species identification and management | NIWA, MPI fisheries data | 1,000–2,000 | Species, catch methods, sustainability guidelines (Doc #78). |
| Pasture management data tables | DairyNZ, Beef + Lamb NZ (Doc #75) | 500–1,000 | Growth rate tables, stocking rate calculators, regional guides. |
4.4 Band 3 — Engineering and Manufacturing (Print Years 1–2)
Estimated volume: 400,000–1,200,000 pages
| Content | Source | Est. pages (master) | Rationale |
|---|---|---|---|
| Materials properties databases | MatWeb (cached), NZ engineering standards | 5,000–10,000 | Tensile strength, thermal conductivity, chemical resistance — essential for machine shop operations (Doc #91) and fabrication. |
| Mechanical engineering handbooks | Machinery’s Handbook, institutional copies | 3,000–5,000 | Thread tables, tolerance charts, gear calculations, bearing specifications. Already exists in some print copies but most NZ workshops rely on digital.15 |
| Electrical engineering reference | NZ wiring regulations (AS/NZS 3000), grid operations data (Doc #67) | 2,000–4,000 | Wiring standards, transformer specifications, generator maintenance. |
| Chemical process data | Perry’s Chemical Engineers’ Handbook, institutional copies | 5,000–10,000 | Process engineering data for local chemical production (Doc #17 and related). |
| Welding procedures and electrode specifications | NZ welding standards, fabrication references | 500–1,000 | Doc #94. |
| Plumbing and water treatment | NZ Building Code references, water treatment chemistry | 1,000–2,000 | Potable water systems, sewage management. |
| Metallurgy and foundry reference | Foundry practice references (Doc #93) | 1,000–2,000 | Alloy compositions, melting points, casting procedures. |
4.5 Band 4 — Navigation, Maps, and Geospatial Data (Print Years 1–3)
Estimated volume: 200,000–600,000 pages (maps are page-intensive)
| Content | Source | Est. pages (master) | Rationale |
|---|---|---|---|
| NZ topographic map series (1:50,000) | LINZ Topo50 series | ~1,000 map sheets | NZ’s complete topographic coverage. LINZ data is digitally accessible. Printed maps are available but not universally distributed.16 |
| NZ nautical charts | LINZ hydrographic data | 200–400 charts | Coastal navigation, harbour approaches, depth soundings. Critical for maritime trade (Doc #139, #141). |
| Celestial navigation tables | Precomputed (Doc #10, #141) | 500–1,000 | Southern Hemisphere star positions, sight reduction tables, almanac data. |
| Tide tables (long-range computed) | LINZ, NIWA tidal models | 200–500 | Pre-computed tide predictions for NZ ports, extended as far forward as data allows. |
| NZ geological maps | GNS Science | 100–200 sheets | Mineral resource locations, fault lines, geothermal areas. |
| Climate and weather reference data | NIWA climate database | 500–1,000 | Historical weather patterns by region — valuable for agricultural planning under changed conditions. |
Why maps are a special case: Maps are among the most toner-intensive items to print (complex graphics, full-page coverage, often require colour) but are also among the most irreplaceable. NZ’s complete topographic coverage exists digitally at LINZ, but physical printed copies of the complete Topo50 series may not exist in sufficient numbers for post-event distribution.17 Printing even a subset — the most operationally critical sheets covering major routes, population centres, agricultural areas, and resource sites — is a high-value use of the printing window.
4.6 Band 5 — Education, Culture, and General Reference (Print Years 2–5)
Estimated volume: 500,000–2,000,000 pages
| Content | Source | Est. pages (master) | Rationale |
|---|---|---|---|
| Mathematics and science textbooks | University curricula, NZ educational publishers | 5,000–10,000 | Secondary and tertiary level science and mathematics — the foundation for all technical recovery. |
| Trade training curricula | NZQA unit standards, polytechnic course materials (Doc #157) | 3,000–6,000 | Carpentry, plumbing, electrical, welding, machining — structured training materials. |
| Te reo Maori language resources | NZ educational resources, dictionaries, grammars, oral history recordings | 1,000–2,000 | Cultural preservation; low resource cost; appropriate only after Bands 1–4 complete. Te reo has undergone significant revitalisation since the 1980s and much supporting infrastructure is digital.18 Priority actions: print the most comprehensive available dictionary and grammar, transcribe key oral history recordings (audio/video) to written text before playback equipment fails, and print immersion school (kura kaupapa) curricula. Allocate specific curation capacity to iwi and Maori organisations — practitioners are best positioned to identify which digital resources add value beyond what oral and community knowledge already preserves. |
| NZ legal and constitutional documents | Parliamentary Counsel Office, NZ Legislation website | 2,000–5,000 | Key statutes, the Treaty of Waitangi / Te Tiriti, Civil Defence Emergency Management Act, essential regulations. |
| NZ history and cultural heritage | National Library, Alexander Turnbull Library digitised collections | Variable | Selective — prioritise taonga (treasured items) and unique NZ content. |
| Encyclopedia / general reference | Locally cached reference works | 10,000–30,000 | A general-purpose knowledge reference — even a partial extract of a comprehensive encyclopedia has enduring value. |
Band 5 is lower priority because: Much of this content exists in NZ’s physical library collections. NZ public libraries hold approximately 8–12 million volumes, and university libraries hold millions more.19 The educational and cultural knowledge base is not as dependent on digital extraction as medical and engineering data. However, specific digital-only content (NZQA unit standards, digitised heritage collections, recent scientific publications) warrants extraction.
5. ESTIMATED PAGE COUNTS AND TONER ALLOCATION
5.1 Total extraction estimate
| Band | Master pages | Copies | Total pages | % of toner budget |
|---|---|---|---|---|
| 1 — Medical | 15,000–30,000 | 50–200 | 750,000–6,000,000 | 15–25% |
| 2 — Agricultural | 8,000–16,000 | 30–100 | 240,000–1,600,000 | 5–10% |
| 3 — Engineering | 17,000–34,000 | 20–50 | 340,000–1,700,000 | 7–12% |
| 4 — Navigation/Maps | 2,000–3,100 sheets | 30–100 | 60,000–310,000 | 5–15% (maps are toner-heavy) |
| 5 — Education/Culture | 21,000–53,000 | 10–30 | 210,000–1,590,000 | 4–8% |
| Recovery Library | 25,000–35,000 | 200–500 | 5,000,000–17,500,000 | 25–40% |
| Operational printing (admin, forms) | Ongoing | Ongoing | Variable | 10–20% |
| Total | ~7–29 million pages | ~100% |
The wide range reflects uncertainty in toner stocks and printing efficiency. At the low end (80,000 cartridges, pessimistic yield), NZ produces approximately 800 million pages total — the extraction programme gets perhaps 500–700 million of those after operational printing needs. At the high end (350,000 cartridges, optimistic yield), NZ produces 5+ billion pages, and the extraction programme is limited by curation speed, not toner.
5.2 Toner allocation framework
Doc #5 establishes the national printing authority and toner rationing framework. The digital-to-print schedule integrates with this through a simple allocation rule:
Priority order for toner allocation:
- Recovery Library production (already scheduled, Doc #5)
- Band 1 extraction (medical — print concurrently with Recovery Library)
- Operational government printing (rationing documents, administrative forms, public communications)
- Band 2 extraction (agricultural — begin as Band 1 completes)
- Band 3 extraction (engineering)
- Band 4 extraction (navigation/maps)
- Band 5 extraction (education/culture)
The critical decision: How much of the national toner supply to allocate to digital extraction versus other uses (administrative printing, document updates, public communications). This document recommends allocating 60–75% of the total toner budget to Recovery Library production and digital extraction combined. The remaining 25–40% covers operational needs. The exact split should be determined by the national printing authority based on actual toner stock levels established by the skills census (Doc #8).
6. COORDINATION WITH EXISTING PRINTING DOCUMENTS
6.1 Relationship to Doc #29 (National Printing Plan)
Doc #29 covers the physical infrastructure of printing — paper production, ink manufacture, print shop operations, and the transition from imported to domestic materials. This document (Doc #132) provides the content schedule that Doc #29’s infrastructure produces. The relationship is:
- Doc #29: How to print (infrastructure, materials, methods)
- Doc #132: What to print and when (content priority, extraction schedule)
- Together: the complete printing strategy for knowledge preservation
6.2 Relationship to Doc #30 (Print Optimization)
Doc #30 specifies the format optimization — fonts, margins, duplex settings, toner-save modes, document quality tiers — that maximise output from finite supplies. This document adopts Doc #30’s specifications directly:
- Band 1 medical references: Tier 1 print quality (full density, no toner-save — accuracy is critical)
- Bands 2–4 reference material: Tier 2 print quality (toner-save on, Garamond 10.5 pt, duplex, reduced margins)
- Band 5 general reference: Tier 2 or Tier 3 depending on expected use life
- Index and catalogue pages: Tier 3 (maximum density)
6.3 Relationship to Doc #5 (Printing Supply Requisition)
Doc #5 covers the requisition and management of existing printing supplies — toner cartridges, paper stocks, printer parts. The digital-to-print schedule is one of the demand streams drawing on the supply that Doc #5 manages. The national printing authority (established by Doc #5) is the decision-maker for toner allocation between competing demands.
7. STORAGE AND DISTRIBUTION OF PRINTED MATERIALS
7.1 Physical storage requirements
The extraction programme will produce an estimated 7–29 million pages of reference material (Section 5.1). At standard A4 dimensions and typical binding, this occupies approximately:
- 70,000–290,000 reams of paper (at 100 pages/ream equivalent, bound)
- Roughly 1,400–5,800 standard archive boxes
- Approximately 50–200 cubic metres of shelving space nationally (assuming standard archive shelving at ~200 pages per linear centimetre, bound in A4 volumes)
This is well within NZ’s existing library and archive storage capacity. NZ’s public library network has an estimated 200+ km of linear shelving nationally, and university libraries add substantially to this total.20 The extraction programme’s storage requirements are a small fraction of available capacity.
7.2 Distribution strategy
Regional hubs: Establish at least 16 regional reference collections, co-located with the regional centres identified in the Recovery Library distribution plan:
- North Island: Auckland, Hamilton, Tauranga, Rotorua, Napier, New Plymouth, Palmerston North, Wellington
- South Island: Nelson, Christchurch, Timaru, Dunedin, Invercargill, Greymouth
- Remote: Gisborne, Whangarei
Each hub receives a complete or near-complete set of all extraction output. Within each region, subset copies (particularly Band 1 medical and Band 2 agricultural) are distributed further to hospitals, clinics, farming cooperatives, and community centres.
7.3 Catalogue and index
Every extracted document must be catalogued — title, source, date of extraction, number of copies, distribution locations. Without a catalogue, a million printed pages are useless if nobody can find the specific reference they need.
The extraction catalogue should follow the structure of the Recovery Library catalogue (catalog.md), with entries organised by subject area, cross-referenced by priority band, and indexed by keyword. Print the catalogue itself in sufficient copies for every distribution hub.
8. CRITICAL UNCERTAINTIES
| Uncertainty | Range | Impact if wrong |
|---|---|---|
| Actual NZ toner stock levels | 80,000–350,000 cartridges (Doc #5) | Determines total extraction volume — at the low end, only Bands 1–2 may be fully printed |
| Electronics degradation rate | 50% failure by Year 3–7 (estimate) | Faster degradation compresses the extraction window; slower gives more time |
| Workforce availability for curation | 20–80 people (depends on competing demands) | Fewer people means slower extraction; may not complete lower-priority bands |
| Hardware condition at event | Unknown age distribution | If NZ’s hardware fleet is older than assumed, the window is shorter |
| Digital content accessibility | Varies by institution | NZ university library digital subscriptions (e.g., Elsevier, Springer, Wiley access via CONZUL consortium) are typically authenticated via internet-dependent licence servers; locally cached content may be DRM-locked. Crown Research Institute data may require institutional credentials. Access keys may be unavailable if key personnel are absent. |
| Quality of cached local content | Unknown | Much digital knowledge was accessed via internet subscriptions; what is actually cached locally vs. requiring internet access is unknown until surveyed |
| Paper stock condition | Depends on storage | Paper stocks may have degraded if stored in humid or uncontrolled conditions |
| Manual printing capability timeline | Year 2–5 for meaningful output (Doc #29) | If domestic paper and ink production is delayed, the gap between laser printing and manual printing widens |

Paper longevity: properly stored acid-free paper can last several hundred years. The Library of Congress and other major archives maintain documents on high-quality paper dating to the 15th century and earlier. Standard ISO 9706 specifies requirements for “permanent paper” suitable for archival use. Modern office paper that meets this standard is widely available.

Two-column layout readability: research in typography and document design consistently shows that line lengths of 45–75 characters per line are optimal for reading speed and comprehension. A two-column A4 layout naturally produces line lengths in this range, while a single-column A4 layout at small font sizes produces lines of 80–100+ characters, which are harder to track visually.

Toner consumption for graphics vs. text: standard laser printer toner coverage for text pages is approximately 5% of the page area. A full-page greyscale image with moderate tonal range may cover 30–80% of the page area, consuming roughly 5–15x the toner of a text page. The exact ratio depends on image density, greyscale distribution, and printer toner-save settings. Based on standard printer manufacturer specifications for page yield at 5% coverage (e.g., HP, Canon, and Xerox cartridge yield ratings).↩︎
