Short answer. New Zealand publishes no law or official guidance on permits, declarations or obligations for a private civil-protection shelter, and no technical standard for blast or fallout shelters. Ordinary building rules apply to any structure, as they would to any other building work. Official preparedness advice focuses on being able to stay at home for three days or more 1.
Is there a New Zealand law on private shelters?
No. No New Zealand law or official guidance on permits, declaration or obligations for a private civil-protection shelter was found. In practice:
- Obligation: none found. New Zealand homes are not required to have a shelter.
- Specific permit or declaration: none found for shelters.
- Technical standard or approval scheme: none published for blast or fallout shelters.
- Applicable rules: ordinary building rules, as for any structure. Phaenyx has not reviewed how they apply to shelters, so it does not say whether a given project needs consent. Ask your council before any work.
What does the government recommend instead?
NEMA's Get Ready advice is to be able to stay at home for three days or more, with at least 9 litres of water per person, food that needs no cooking and an emergency toilet, plus a grab bag for each person 1. There is no public network of blast or fallout shelters; during an emergency, councils open Civil Defence Centres for welfare support 2. See Emergency supplies in New Zealand and Public shelters in New Zealand.
What should I know before planning a shelter?
Anything underground or load-bearing needs a qualified structural engineer; Phaenyx gives no construction instructions. Background reading, with its own sources:
- What is a shelter's protection factor?
- How much fresh air does a shelter need?
- How does NBC air filtration work in a shelter?
- Can you bury a shipping container as a shelter?
