Quick answer: seven things drive the price of a fence — the material, the height, the total length, the number of gates and corners, the ground conditions, site access, and whether an old fence needs removing. Two jobs of the same length can differ by thousands because of slope, access and gates, which is why a fair quote always follows a site visit rather than a guess over the phone.
Understanding what moves the number helps you plan a realistic budget and compare quotes properly. Here are the seven big cost factors.
1. Material — the Biggest Single Lever
Material sets the baseline everything else adjusts from. Treated-pine palings sit at the affordable end and always will, because the materials are commodity items stocked everywhere and any competent crew can build with them. Colour-coated steel panels and aluminium slat systems cost more because they are manufactured products with proprietary components. Masonry and SmartWall systems sit higher again.
Within a material there is a second spread that quotes rarely make visible. Timber grade, paling thickness, rail size and post dimensions can all vary between two quotes described identically as "timber paling fence", and the cheaper one is frequently cheaper because of exactly those choices rather than better buying.
The question worth asking every quoter is not what material but what specification — post size, post spacing, rail size, timber grade in ground and above it. It takes one sentence and it sorts genuinely competitive quotes from ones that have simply specified less fence.
2. Height — It Costs More Than Proportionally
People reasonably assume a two-metre fence costs about eleven percent more than a 1.8-metre one, because that is the extra material. It does not, and understanding why helps you decide whether the extra height is worth it.
A taller fence catches more wind, and wind load rises faster than height does. That means longer posts, deeper holes, more concrete, and sometimes closer post spacing to carry the load. All of that is groundwork, which is the labour-intensive part of the job, so a modest increase in height can produce a disproportionate increase in cost.
The practical implication is that if you want extra height in one place — to solve a specific overlooking problem — it is usually far cheaper to build the boundary at standard height and add a short taller section or a freestanding screen where you actually need it, rather than lifting the whole run.
3. Length — and Why Short Runs Cost More Per Metre
Length is the obvious multiplier, but the per-metre rate is not constant, and this catches people comparing quotes between properties. Every job carries fixed costs that do not scale — travel, setting out, mobilising tools and materials, the site visit, the paperwork. On a long run those spread thin; on a short one they dominate.
So a ten-metre fence will almost always come in at a higher rate per metre than a sixty-metre fence of identical specification, and that is not a contractor taking advantage. It is the same reason a small plumbing job has a call-out fee.
Continuity matters as much as total length. One long uninterrupted run is more efficient than the same metres broken into four disconnected sections with corners, ends and set-outs at each. If you are fencing in stages, doing one continuous boundary at a time costs less than doing bits of several.
4. Gates and Corners — Each Is a Small Project
A gate is not a section of fence with hinges on it. It needs oversized posts set deeper than the line posts because a gate post carries a permanently offset load, a braced frame, and hardware rated for the weight and width. It is genuinely a small project inside the larger one, and every quote should show it as its own line.
Driveway gates escalate from there, and automation escalates again — motors, safety photocells, control gear, and power run to the gate. Planning the power supply while the ground is open is dramatically cheaper than trenching through a finished driveway later, which is why it is worth deciding about automation before the fence goes in rather than after.
Corners cost for a related reason. A corner post takes load from two directions and needs to be more substantial, and corners also generate offcuts and extra set-out time. A fence with five corners is meaningfully more expensive than a straight run of the same total length.
5. Ground Conditions — Clay, Rock and Water
Auckland's heavy clay is slow to dig — hard when dry, greasy when wet — and it drains poorly, which often means extra drainage material under posts. Compared with free-draining soil, the same number of holes simply takes longer, and labour is what you are paying for.
Rock is the genuine wildcard, and it is why good contractors are careful about quoting sight-unseen. Buried rock, old concrete footings, previous foundations and construction fill can each turn a straightforward hole into a long one. Nobody can see this from the street, which is why site visits exist.
Slope adds its own cost. A sloping boundary needs stepped or raked construction, custom post heights, and gap management under each step — all extra setting-out and cutting. Where the fall is steep enough to need retaining, that is a different and considerably larger job again.
6. Site Access — the Invisible Multiplier
Access rarely appears as a line on a quote and frequently moves the total more than the material choice does. Where a truck can tip materials beside the fence line and a machine can dig, a crew moves fast. Where every post, every bag of concrete and every paling has to be carried down a narrow side path, the same fence takes far longer.
Rear boundaries on tight urban sections are the usual culprit, along with properties down shared driveways, sites with steps between the street and the fence line, and boundaries where the only access is through a neighbour's property — which introduces a permission conversation as well as a logistics one.
It is worth flagging access honestly when you ask for a quote. A contractor who discovers the real access on the morning of the job either absorbs it or has an awkward conversation, and neither produces a good outcome for anyone.
7. Demolition and Disposal
Removing an old fence is real work and it produces a genuinely heavy load — palings, rails, posts, concrete footings and old fixings. Digging out concrete footings is the slow part, and disposal costs are charged by weight, so an old fence with substantial concrete costs meaningfully more to remove than one without.
This is the single most common thing left out of a quote, and it is a favourite way for a cheap-looking number to become an expensive one. Always confirm explicitly whether demolition, cartage and tip fees are included.
Some material can be diverted rather than dumped — steel and aluminium components are recyclable, concrete can go to hardfill, and sound above-ground timber sometimes has a second life. Treated timber cannot be burned under any circumstances and has to go to landfill.
Comparing Quotes on the Same Basis
When two quotes differ substantially, the difference is almost never the profit margin. It is the specification, the inclusions, or something one contractor has seen on site that the other has not. Before assuming one is expensive, check post size and spacing, timber grades, whether gates are itemised, and whether demolition, disposal and GST are in or out.
Be particularly careful with quotes given over the phone without a site visit. They cannot account for ground, slope or access, which are three of the seven factors above — so a phone number is a guess that will be revised, and it is usually revised upward.

Frequently Asked Questions
Material, height, length, gates and corners, ground conditions, site access, and demolition of the old fence. Material sets the baseline, but ground and access are the ones that quietly move a total the most — and they're the ones a phone quote can't see.
Usually specification rather than margin. Post size, post spacing, rail size and timber grades can all differ between two quotes both described as "timber paling fence". Ask each quoter for those four numbers and the comparison becomes real.
Because wind load rises faster than height, so a taller fence needs longer posts, deeper holes, more concrete and sometimes closer post spacing. That's all groundwork, which is the labour-intensive part — a modest height increase can move the cost disproportionately.
Fixed costs that don't scale — travel, setting out, mobilising tools and materials, the site visit. On a long run those spread thin; on a ten-metre run they dominate. It's the same reason a small plumbing job carries a call-out fee.
Not always, and it's the most common omission. Demolition produces a heavy load and disposal is charged by weight, with old concrete footings the slow, expensive part. Confirm explicitly whether demolition, cartage, tip fees and GST are included.
A gate needs oversized posts set deeper than line posts to carry a permanently offset load, a braced frame, and hardware rated for its weight and width. It's a small project inside the job. Automation adds motors, safety gear and power — plan that before the ground is closed up.
Not really. A phone estimate can't see ground conditions, slope or access, which are three of the seven cost factors, so it's a guess that gets revised — usually upward. A site-based written quote is the only number worth comparing.
