New Zealand household resilience
New Zealand Civil Defence Get Ready advises storing water for three days or more, with at least three litres of drinking water per person per day.
Local Civil Defence Emergency Management groups may provide additional hazard-specific advice for your area.
Use the global resilience check
The main calculator lets you combine electricity, gas/fuel, mains water, food-supply and communications disruptions, then compares your stored water, shelf-stable food and backup phone energy with the selected planning horizon.

What limiting resilience does — and does not — mean
The headline day figure identifies the earliest modelled resource limit in the selected scenario. The secondary 0–100 scenario score summarises broader coverage. Neither is a forecast of how long it is safe to remain at home, and neither replaces emergency services, public-health guidance, evacuation orders or professional advice.
Use the same plan in your preferred units
The global calculator keeps its country guidance pack separate from display units. You can use the automatic country default or switch water quantities between litres, US gallons and UK imperial gallons without changing the underlying planning target.
What the New Zealand country pack changes
The New Zealand pack uses Civil Defence Get Ready guidance of at least three litres of drinking water per person per day and defaults to metric units. As with the other country packs, changing display units only converts the quantity.
Local Civil Defence Emergency Management groups can provide hazard-specific information. The household calculator is intended to complement that local planning by showing how water, food, stored power, heating and communications interact.
What stays the same globally
The dependency engine, limiting-resilience calculation, device-load planner, food-usability logic, copy controls and printable plan use the same method in every supported country. Localisation changes the guidance source, water baseline, emergency references and default display units rather than creating a different product.
