New Zealand's weather is famously changeable — a single day can swing from bright sunshine to driving rain and back again, regardless of the season. Two main islands stretched across more than 13 degrees of latitude, combined with mountain ranges and surrounding oceans, mean conditions vary enormously from region to region at any given time. This variability also brings genuine hazards: ex-tropical cyclones, severe thunderstorms, heavy rain and flooding, snow, and strong winds can all occur with little warning, making it worth checking active warnings before heading out or making plans.

◆  About New Zealand Seismicity

New Zealand sits on the boundary of the Pacific and Australian tectonic plates — one of the most seismically active zones on Earth. The country experiences around 14,000–15,000 earthquakes per year, of which roughly 100–150 are felt by people. The Alpine Fault, running 600 km along the South Island, is considered overdue for a magnitude 8+ rupture. Other major fault systems include the Hikurangi subduction zone (east of the North Island), the Wellington Fault, and the Wairau Fault.

A major Alpine Fault earthquake could cause widespread infrastructure damage across the South Island, with potential isolation of communities for weeks to months. NEMA's "AF8" scenario planning estimates up to 80% of South Island road bridges could be damaged. Full earthquake history is available at GeoNet.org.nz.

Electricity Generation
◆  Transpower Grid Notices — How They Work
CAN
Customer Advice Notice
Issued when residual generation forecast drops below 200 MW. Can be issued from one week to one hour out. Earliest warning level — take note, no action yet required.
WRN
Warning Notice
Issued when residual generation forecast falls below zero — meaning more power demanded than can be supplied. Demand reduction may be requested from large industrial consumers.
GEN
Grid Emergency Notice
Issued when a generation deficit is confirmed less than one hour out. May require controlled load shedding (rolling blackouts) by lines companies.

NZ generates approximately 80–85% of electricity from renewable sources (hydro, geothermal, wind). During dry years, hydro lake levels drop and thermal (gas/coal) generation at Huntly increases to compensate. Total NZ installed capacity ~10,000 MW. Source: Electricity Authority, company reports.

Future Capabilities
◆  Federated Outage Map — Pilot Project
Project: Federated Electricity Outage Map — Pilot Project
Lead: Digital Built Aotearoa Foundation
Funding: National Emergency Management Agency (NEMA)
Goal: Combine real-time outage data from all electricity distribution businesses (EDBs) into a single public map — equivalent to a 111 for power outages.
Status: Pilot under development as of 2025. No public URL yet. When available, data will be linked here.

Currently, each of New Zealand's ~28 electricity distribution businesses (Vector, Powerco, Aurora, Orion, etc.) publishes outage data separately, often in incompatible formats. The Federated Outage Map project aims to aggregate these into a unified real-time feed accessible to the public and emergency management agencies.

Import Reliance by Food Category
Rice
~100%
NZ grows no commercial rice. Entirely imported, primarily from Australia, Thailand, and the US.
Wheat & Flour
~90%
Small domestic wheat crop (Canterbury). Most flour, bread flour, and pasta wheat is imported from Australia.
Canned & Processed Foods
~85%
Canned vegetables, soups, packaged goods largely imported. Domestic canning industry very small.
Sugar & Confectionery
~100%
No domestic sugar production. All raw and refined sugar imported from Australia, Fiji, and the Philippines.
Cooking Oils
~95%
Palm oil, canola oil, sunflower oil largely imported. Limited domestic seed oil production.
Fruit & Vegetables (fresh)
~35%
Off-season imports significant. NZ exports kiwifruit, apples; imports bananas, tropical fruit, some vegetables in winter.
Meat (beef, lamb)
~5%
NZ is a major meat exporter. Domestic meat supply is robust. Some specialty cuts imported.
Dairy Products
~5%
NZ is the world's largest dairy exporter per capita. Domestic supply is more than sufficient.
Seafood
~15%
Some species and processed seafood imported. NZ EEZ is extensive; domestic harvest significant.
◆  Resilience Assessment
ScenarioRisk LevelKey VulnerabilityEstimated Domestic Supply
14-day supply disruption (e.g., major shipping stoppage) MODERATE Rice, flour, cooking oils, sugar exhausted within weeks Meat, dairy, vegetables adequate
3-month supply disruption (e.g., global shipping crisis) SEVERE Broad grocery shortages; rationing likely for staple carbohydrates Protein and dairy self-sufficient; caloric gap without wheat/rice
1-year isolation (extreme scenario) EXTREME Fertiliser import dependency would limit next harvest cycles NZ could feed itself on protein; carbohydrate production would need to scale dramatically
◆  Key Facts & Data Sources

New Zealand exports approximately NZ$50 billion in food and agricultural products per year, making it one of the world's most food-productive nations per capita. However, its domestic grocery market is highly import-dependent for processed and shelf-stable foods. The country imports approximately 15–20% of its total food supply by value, concentrated in staple foods and processed goods.

The primary food security risk in NZ is a prolonged disruption to shipping routes, particularly from Asia and Australia. NZ's geographic isolation means that a 14-day shipping delay is typical in any major port disruption, and most grocery distribution centres carry 4–6 weeks of stock in normal conditions.

Fertiliser import dependency is a secondary risk: approximately 90%+ of fertiliser used in NZ is imported (primarily urea from China and Russia, superphosphate from Morocco). A multi-year fertiliser supply disruption would significantly reduce farm production within 2–3 growing seasons.

Emergency Preparedness Guidance
🎒
Emergency Kit
NEMA recommends 3 days minimum of supplies: water (3L/day/person), food, first aid, torch, radio, phone charger, medications, cash, warm clothing, and important documents.

🌊
Tsunami
If you're at the coast and feel a long or strong earthquake: don't wait for official warning. Go immediately to high ground or inland. Natural warning = 20 minutes or less before a local tsunami.
Tsunami guidance ↗
🏚️
Earthquake
Drop, Cover, Hold: get under a sturdy table, cover head and neck, hold on until shaking stops. After: expect aftershocks. Don't use lifts. Check for gas leaks and structural damage before re-entering buildings.
Earthquake guidance ↗
🌋
Volcanic Eruption
Follow evacuation orders immediately. Ash fall: stay inside, seal gaps, wear N95 masks if outside. Avoid low-lying areas near active vents (lahar risk). Lahars travel fast and look like concrete.
Volcano guidance ↗
🌀
Cyclone & Flooding
Monitor MetService. Move valuables and whiteware above floor level. Know your evacuation route. Never drive through floodwater — 300mm can float a car. Don't camp near rivers when heavy rain is forecast.
Storm guidance ↗
🔥
Wildfire
Know your local fire weather. Evacuation orders: leave early — don't wait until you can see flames. If trapped: call 111, stay low, seal gaps in your vehicle, turn on headlights and hazard lights.
