Quick answer: gate hardware is where people under-spend and pay for it later — the hinges, latch and fixings take all the stress of daily use, so they need to be rated for the gate's weight and made to survive Auckland's damp, coastal air. Choose heavy-duty hinges matched to the gate, a reliable latch (self-closing and child-safe for pool gates), and corrosion-resistant materials like stainless or hot-dip galvanised. Good hardware is the difference between a gate that swings true for years and one you're forever adjusting.
A gate is only as good as the bits that make it move and hold shut. Here's how to choose hardware that lasts.
Why Hardware Is Where Fences Actually Fail
A boundary fence is a static structure. It stands there, and provided the posts are right it goes on standing there. A gate is a machine. It moves thousands of times a year, and every one of those movements loads a handful of small metal components that cost a fraction of the fence budget.
That mismatch is why gate problems dominate fence complaints. Nobody rings about a paling. They ring because the gate drags on the ground, won't latch without a lift and a shove, has dropped at the latch stile, or has seized solid in the salt air. In almost every case the timber is fine and the hardware was the weak link.
The useful way to think about it is that hardware is not an accessory to the gate — it is the part of the gate that does the work. Spending an extra amount here that looks disproportionate against the total fence cost is one of the highest-return decisions in the whole job.
Hinges: Size Them to the Gate, Not the Post
Hinges carry the entire weight of the gate, and they carry it as a rotating load applied at one edge — which is a far harder job than simply holding something up. The number one rule is to size the hinge to the gate's actual weight and width, and when in doubt go up rather than down.
Width matters as much as weight, and people miss this. A wide gate applies enormous leverage to its hinges even if it isn't especially heavy, because the load acts at the far end of a long arm. A wide lightweight gate can punish hinges harder than a narrow heavy one, which is why wide gates so often need three hinges rather than two.
Adjustable hinges are worth every cent. Timber moves, ground settles, and posts shift a little over years — with adjustable hinges you re-level the gate with a spanner in five minutes. Without them, the same correction means unscrewing and rehanging the whole gate, which is why so many sagging gates simply stay sagging.
The Real Cause of a Dropping Gate
When a gate drops, most people blame the hinges, and sometimes they are right. But there are three other causes worth ruling out, because replacing hinges will not fix any of them.
The first is the post. A gate post carries a permanently offset load pulling it toward the gate, which is a different load case from a normal fence post and needs a deeper, better-concreted footing. If the post itself is leaning, the gate drops no matter what hinges are on it — and the giveaway is that the gap at the top of the latch stile has opened up into a wedge shape.
The second is bracing. A gate frame is a rectangle, and rectangles rack out of square unless something triangulates them. A diagonal brace must run from the bottom of the hinge side up to the top of the latch side, so it works in compression. Fitted the other way it does nothing, and this is one of the most common DIY gate mistakes. The third is simply the fixings — screws into end grain will pull out eventually, however good the hinge.
Latches for How the Gate Is Actually Used
Latch choice deserves more thought than it usually gets, because it is what makes a gate pleasant or irritating to live with. Start from how the gate gets used: which side you approach from, whether you can reach through, and whether your hands are usually full of shopping, tools or a child.
A gravity latch is simple and reliable and is the default for a standard side gate. A ring latch operable from both faces suits a gate you pass through in both directions. A drop bolt into the ground is what actually holds a double gate steady, because the leading edges have nothing else to fix to. A lockable latch or keyed bolt is the answer where security matters — though be realistic that a gate latch is a deterrent rather than a barrier.
The detail that turns a good latch into a bad experience is alignment. A latch that needs the gate lifted, pushed or persuaded is a latch fighting a gate that has dropped or a striker set in the wrong place. Fix the geometry rather than living with the technique.
Pool Gates: Where Hardware Is Compliance
Around a pool, gate hardware stops being a convenience question and becomes a legal one. A residential pool gate must be self-closing from any position, self-latching, and the latch must sit out of reach of a small child. The gate must open away from the pool area, and the barrier around it must have no footholds in the non-climbable zone.
The self-closing requirement is the part that fails in service. A hinge that closed the gate reliably on day one can weaken, or become obstructed by a stone, a build-up of debris, or a settled path. A gate that closes from halfway but not from fully open is not compliant, and that is exactly the failure mode owners stop noticing.
Councils inspect residential pool barriers periodically, so a degraded gate closer is a compliance problem waiting to be found. Test it properly: open the gate fully, let go, and confirm it closes and latches on its own without any help. Do it a few times a year, not just when an inspection is due.
Materials: Stainless, Galvanised, and What Fails
Gate hardware lives outdoors permanently, and in Auckland — especially anywhere near the coast — cheap fittings rust, seize and bleed rust stains down the gate within a season or two. Stainless steel and hot-dip galvanised are the two finishes that genuinely survive, and the extra cost is trivial against the cost of replacing a seized latch and a stained gate.
Not all galvanising is equal. Hot-dip galvanising builds a thick metallurgically bonded coating that lasts for years outdoors. Electroplated zinc looks similar in the packet and does not survive comparable exposure. Ask which one you are getting, because the visual difference on the shelf is small and the difference in service life is not.
The other trap is mixing metals. Fixing stainless hardware with galvanised screws — or the reverse — sets up galvanic corrosion, and in salt air that runs fast. It is also why a good hinge on an aluminium gate can still bleed rust: the hinge is fine, the fasteners aren't. Keep the fastener metallurgy consistent with the fitting.
Maintenance, and Getting It Specified Right
Gate hardware asks for very little and repays it generously. Once or twice a year, check the fixings are still tight, lubricate the hinges and moving latch parts, clear debris from the closing arc, and — near the coast — rinse the salt off. That is the entire maintenance regime, and it prevents most of the failures described above.
The one thing to act on immediately is any binding or dragging. A gate that has started to catch is applying loads to hinges, screws and frame that none of them were designed for, and left alone it will progress from a nuisance to a rehang or a rebuild.

Frequently Asked Questions
Hinges rated for the gate's weight and width, a latch suited to how you actually use the gate, and corrosion-resistant fixings. Adjustable hinges are worth insisting on. Pool gates additionally need self-closing, self-latching hardware with the latch out of a child's reach.
Four possible causes, and hinges are only one. Check whether the gate post itself is leaning under the offset load, whether the frame has a diagonal brace running from the bottom hinge side up to the top latch side, whether the fixings have pulled out of end grain, and only then the hinge size.
From the bottom of the hinge side up to the top of the latch side, so it works in compression and pushes the latch corner up. Fitted the other way round it's in tension and does essentially nothing — one of the most common DIY gate mistakes.
Two for a standard gate, three for anything heavy or wide. Width matters as much as weight, because a wide gate applies leverage at the end of a long arm — a wide lightweight gate can punish hinges harder than a narrow heavy one.
It must be self-closing from any position, self-latching, with the latch out of a small child's reach, and it must open away from the pool. Test it by opening fully, letting go, and confirming it closes and latches unaided — closing from halfway is not compliant.
Stainless steel or hot-dip galvanised — and hot-dip specifically, not electroplated zinc, which looks similar on the shelf and doesn't last outdoors. Keep the fastener metal consistent with the fitting, because mixing metals causes galvanic corrosion that runs fast in salt air.
Once or twice a year: check the fixings are tight, lubricate hinges and moving latch parts, clear debris from the closing arc, and rinse off salt near the coast. Deal with any binding or dragging immediately — a catching gate loads its hinges and frame far beyond what they were designed for.
