Installing a pool fence is one of the smartest decisions any pool owner in New Zealand can make. Not only does it provide safety for your family, but it also ensures compliance with the Fencing of Swimming Pools Act 1987, which requires all pools to be securely fenced.

While hiring a professional installer is the easiest way to guarantee compliance, many homeowners choose the DIY route. A DIY pool fence can save money and give you the satisfaction of completing the project yourself. However, it’s also an area where mistakes are common. Unfortunately, even small errors can mean your fence fails an inspection, putting both safety and compliance at risk.

In this article, we’ll look at the most common DIY mistakes pool owners make and show how the right aluminium pool fences and gates from SD Aluminium can help you avoid them.

Mistake 1: Incorrect Fence Height

One of the most frequent errors is choosing panels that don’t meet the minimum legal height. A pool fence that’s even a few centimetres too low won’t pass inspection, no matter how solid it looks.

Solution: Measure carefully before purchasing and select panels that are manufactured with compliance in mind.

  • Aluminium Fence GM-SDWL-08 – $92.00

    A cost-effective panel that provides the required height and a sleek look for smaller pool areas.

  • Aluminium Fence GM-SDWL-26 – $230.00

    A taller, premium option designed for larger pools or homeowners who want extra assurance.

By choosing pre-fabricated aluminium panels, you remove the risk of cutting or modifying fences incorrectly.

Mistake 2: Gaps That Are Too Wide

Another common compliance issue is leaving gaps wider than 100mm between vertical bars or at the base of the fence. Children can slip through, making the pool area unsafe.

Solution: Use panels that are designed with correct spacing to eliminate guesswork.

When installed properly, these panels give you peace of mind that your pool fence won’t fail inspection.

Mistake 3: Weak or Improper Gate Latching

Perhaps the single most common reason DIY fences fail compliance checks is gate latching. A pool gate must be self-closing and self-latching. If your gate swings open or doesn’t lock securely, it’s not compliant.

Solution: Always use gates that come with self-closing hinges and latches designed for pool safety.

  • Aluminium Gate GM-SDWL-07 – $161.00

    Lightweight yet sturdy, with a latch system designed for safety.

  • Aluminium Gate GM-SDWL-26 – $402.50

    A premium gate with heavy-duty construction, perfect for homeowners who want maximum security and long-term durability.

Properly installed gates are the key to passing compliance checks.

Mistake 4: Poor Ground Preparation

DIY installers sometimes rush into setting posts without leveling the ground. This can lead to uneven panels, wobbly posts, or gaps underneath the fence.

Solution: Always clear and level the installation area before starting. Set posts in concrete where required to ensure long-term stability.

  • Aluminium Fence GM-SDWL-53 – $74.75

    An affordable entry-level option that works well for smaller projects, as long as the ground is prepared correctly.

  • Aluminium Fence GM-SDWL-53-1 – $97.75

    A slightly larger version that provides more coverage and is still easy to install on level ground.

Good preparation ensures your pool fence lasts for years without shifting or leaning.

Mistake 5: Mixing Materials That Don’t Last

Some DIY projects combine timber, untreated steel, or other materials with aluminium panels. The problem is that these materials often warp, rust, or deteriorate quickly, especially in New Zealand’s coastal climate.

Solution: Stick with powder-coated aluminium and stainless-steel hardware for durability.

Aluminium is lightweight, strong, and virtually maintenance-free—ideal for pool environments.

Mistake 6: Ignoring the Law

Finally, some DIYers focus only on looks and forget about compliance altogether. A pool fence might look sturdy and attractive but still fail New Zealand’s safety regulations. Non-compliance can lead to fines and costly rework.

Solution: Choose products that are manufactured specifically for compliance.

Buying from trusted suppliers like SD Aluminium ensures your fence isn’t just stylish, but also safe and legal.
