Do I need consent to build a fence in NZ?
Short answer
Most domestic fences in NZ don't need a building consent — Schedule 1 of the Building Act exempts fences and walls under 2.5 metres. Pool fences are a separate regime with stricter rules. The Fencing Act 1978 deals with the civil side of who pays for a boundary fence, separate from any consent question. District plans sometimes set additional rules on height in front yards or near intersections.

The 2.5m exemption — and the gotchas
Schedule 1 of the Building Act exempts fences and walls under 2.5m from building consent. That's the height of the structure overall, not just the visible above-ground part.
If the fence is on top of a retaining wall and the combined structure is over 2.5m (or the retaining wall itself is over 1.5m), the retaining wall portion needs consent.
Pool fences are different
Pool fences must comply with the Fencing of Swimming Pools requirements (now embedded in the Building Act). Specific rules about height (1.2m minimum), gaps, gate self-closing, and the 'non-climbable zone'. Always requires consent.
Boundary fences forming part of a pool barrier are subject to the same rules.
Who pays — the Fencing Act
The Fencing Act 1978 sets the rule that adjoining owners share the cost of an adequate fence between their properties, usually 50-50. Notice procedures and dispute resolution paths are in the Act.
If your neighbour wants a fancy fence and you want a basic one, you only have to contribute toward the 'adequate' standard. Anything above that is on them.
Knowing the rules is half the job. The other half is knowing who you're hiring. Check any NZ builder against the public record: company status, licensing and insolvency notices, from the official NZ sources.
