If you live anywhere from Mount Maunganui to Papamoa, Te Puke or Waihi, your fence has a harder job than most. Salt-laden coastal air, strong onshore wind and intense Bay of Plenty sun all work against it year-round. So when it comes time to choose between aluminium and timber fencing, the right answer often comes down to how your property copes with the coast.
Here’s an honest, side-by-side look from a team that’s been building fences across the Bay of Plenty since 2005.
The short answer
For most coastal Bay of Plenty properties, aluminium fencing is the better long-term investment — it doesn’t rot, warp, rust or need repainting, and it shrugs off salt air. Timber still wins on natural warmth and upfront cost, and it’s a great choice for sheltered, inland sections where you love the look and don’t mind the upkeep.
Now let’s break down why.
Lifespan and durability
Timber fencing typically lasts 10–15 years in New Zealand conditions, and noticeably less when it’s exposed to constant salt spray and wind. Coastal moisture speeds up rot at the posts and rails, and the sun dries and cracks the boards.
Aluminium fencing, by contrast, is built for exactly these conditions. It won’t rot or corrode the way steel can, and a quality powder-coated finish protects it from UV and salt. At TBGF we use 100% New Zealand aluminium finished with a Duratec powder coat, backed by a 5-year guarantee — that’s the difference between a fence that fades in a few summers and one that still looks sharp a decade on.

Maintenance
This is where the two really separate.
Timber needs ongoing care: staining or oiling every couple of years, replacing rotten palings, and re-securing boards that warp or cup. On the coast, that maintenance cycle gets shorter.
Aluminium is close to maintenance-free. An occasional hose-down to rinse off salt build-up is genuinely all most of our clients ever do. If you’d rather spend your weekends at the beach than sanding a fence, aluminium is the easy call.
Appearance
Timber offers a natural, warm look that many homeowners love, and it can be stained to almost any tone. The trade-off is that it weathers — the fresh look fades unless you keep on top of it.
Aluminium gives a clean, modern, architectural finish in a wide range of colours that stay consistent for years. It also suits contemporary Bay of Plenty homes and pairs neatly with matching gates and automation.
Cost
Timber usually has a lower upfront cost, which is why it’s still popular for long boundary runs and budget-conscious projects.
Aluminium costs more to install initially, but because it lasts longer and needs almost no maintenance, it often works out cheaper over the life of the fence — no repainting, no repairs, no full replacement in 12 years’ time. It’s the classic “buy once, cry once” scenario.
Which should you choose?
Choose aluminium if you’re on or near the coast, you want a modern look, you value low maintenance, or you’re fencing a pool (where a durable, compliant fence is non-negotiable).
Choose timber if you’re on a sheltered inland section, you love the natural look, you’re working to a tighter upfront budget, and you’re happy to maintain it.
Still unsure? The best fence depends on your exact site, exposure and budget — and we’re happy to walk your property and give you a straight recommendation.
Frequently asked questions
Does aluminium fencing rust?
No. Aluminium doesn’t rust the way steel does, and a quality powder-coat finish protects it from salt and UV — which is why it performs so well on the Bay of Plenty coast.
Is aluminium fencing more expensive than timber?
Aluminium usually costs more upfront, but with no repainting, repairs or early replacement, it typically costs less over the full life of the fence.
What’s the best fence for a coastal property in Tauranga?
For salt-air exposure, powder-coated aluminium is generally the most durable and lowest-maintenance option. Timber can still work well on sheltered sites.
How long does aluminium fencing last?
With a quality powder-coat finish, aluminium fencing can last decades with minimal upkeep. TBGF backs its Duratec finish with a 5-year guarantee.
