If you’ve got a pool at home in New Zealand, you need to know the rules about fencing. It’s not just about keeping things looking tidy—it’s the law, and it’s all about safety, especially for kids.

Here’s what you need to know.

Why Do You Even Need a Pool Fence?

New Zealand law says that any pool with water deeper than 400mm (40cm) needs a proper fence to stop unsupervised kids from getting in. That includes in-ground pools, above-ground pools, and even some large inflatable pools.

It’s all in the Building (Pools) Amendment Act 2016, which replaced the old Fencing of Swimming Pools Act. If you’re wondering where to read the official details, check out the rules on the Building Performance website.

What Kind of Pool Fence is Required?

It’s not just about having a fence—it has to be the right kind of fence.

Here’s what matters:

• Height: At least 1.2m high all the way around. No short cuts.
• No Climbing Hazards: Things like BBQs, planters, or furniture near the fence? They can’t help someone climb over. Make sure they’re at least 1.2m away.
• Gate Rules: The gate has to open outward, close by itself, and latch shut automatically. No propping it open!
• No Gaps: Any gaps under the fence or between bars must be less than 100mm. Basically, if you could squeeze a basketball through, it’s not compliant.
• Direct Access from the House? If your house opens straight onto the pool, you might need a lockable door or alarm system instead of a fence. But check with your local council.

If you’re not sure whether your fence is up to scratch, your local council has inspectors who can help.

Who Checks If Your Pool Fence is Legal?

Councils do inspections every 3 years to make sure your fence still meets the regulations. If they find issues, you’ll need to fix them—otherwise, you could get fined.

Where to Get a Compliant Pool Fence

Need a fence or a gate that meets the rules? Here are some options:

• Bunnings NZ – They’ve got pool fencing kits and gates.
• Mitre 10 – Another good option for DIY pool fencing.
• Fencing New Zealand – For customised fencing solutions that meet legal requirements.
• Glass Vice – If you want a sleek, glass pool fence.

If you don’t want to deal with installation yourself, hire a licensed fencing contractor to do it right the first time.

What About Temporary or Inflatable Pools?

Even those cheap inflatable pools that seem harmless? If they hold more than 400mm of water, they need a fence too. That means if you’re planning to leave one up for more than a few days, you’ll need to sort out a barrier.

A safer bet? Empty it when you’re done.

Don’t Risk the Fines

If your pool isn’t fenced properly, you could get slapped with a fine—sometimes $500 or more. But more importantly, an unsafe pool is a drowning risk.

The rules might seem like a hassle, but they’re there for a reason. In New Zealand, kids under five are particularly at risk, and good pool fencing prevents accidents.

So, if you’re setting up a pool or checking your existing one, take a few minutes to make sure it’s all legit. If you need advice, your local council is the best place to start. They can clarify the details and point you in the right direction.

Got a pool? Keep it safe, follow the rules, and enjoy it—without the stress.
