Corner Site Fencing in Nelson: The Rule That Catches Homeowners Out

You live on a corner section in Stoke, or Richmond, or Nelson central. You want a fence along both road frontages. You’ve asked a fencing contractor about it and been told there are “corner site rules” — but the explanation was vague and you left the conversation not much clearer than when you started.
The corner site visibility splay rule is one of the more specific pieces of Nelson fencing regulation, and it catches homeowners out regularly — sometimes after the fence is already built. This post explains exactly what the rule requires, where it applies, and what your options are within it.
Why corner sites have different fencing rules
At an intersection, drivers and pedestrians need to see each other before they arrive at the crossing point. A solid fence built right into the corner of a property removes that sightline. The result is a blind corner — vehicles pulling out can’t see pedestrians, cyclists approaching from the side road can’t be seen by drivers on the main road.
Nelson City Council’s visibility splay rule exists specifically to prevent this. It’s not an arbitrary planning restriction — it’s a road safety requirement, and understanding the reason behind it makes the rule easier to work with.
What the Nelson City Council rules actually say
For corner sites within Nelson City Council’s jurisdiction, the Nelson Resource Management Plan requires a visibility splay to be maintained at the intersection of the two road frontages.
The visibility splay is defined as a triangle formed by measuring 1.5 metres along each road boundary from the point where they meet (the corner). Within that triangle, no structure may exceed 1.0 metre in height.
Outside the splay — once you’ve moved 1.5 metres along each road boundary from the corner — the standard road frontage rules apply. For most residential streets (unclassified roads) in Nelson, this means:
- Solid fencing up to 1.2m permitted
- Fencing up to 1.8m permitted if entirely visually permeable
On side and rear boundaries, 1.8m solid is permitted without restriction.
To put this in plain terms: imagine cutting a triangle off the corner of your section, with the triangle sides each 1.5 metres long. Inside that triangle, your fence can’t go above 1.0m. Outside the triangle, your standard road frontage rules apply. And once you’re past the road frontage and onto your side boundary, you can go to 1.8m solid.
What the splay means in practice for your fence
Here’s a common Nelson corner site scenario to make this concrete.
A homeowner on a corner site in Stoke wants a fence along both road frontages for privacy. They’d like 1.8m if possible, or at least as much height as they can get.
What they can actually achieve under permitted rules:
In the corner triangle (1.5m along each road boundary from the corner): maximum 1.0m. Any material, any style — just nothing over 1.0m in height.
On the road frontage beyond the triangle (unclassified road): maximum 1.2m solid, or up to 1.8m if the fence is entirely visually permeable (gaps visible through the full face of the fence).
On side and rear boundaries: 1.8m solid, no restriction.
The practical result is a fence that steps: low in the corner triangle, rising to the permitted frontage height once outside the triangle, and then potentially rising again to 1.8m on the side boundary. Done well, this step design can look intentional and attractive. Done without thought, it can look like a mistake.
The step design requires some planning before the posts go in. The post at the transition from the triangle to the road frontage needs to be correctly positioned so the step happens in the right place, and the fence heights on either side of the step need to be clean and level.
Options within the rules
A continuous low fence at 1.0m or 1.2m along both frontages. The simplest option. A 1.2m solid timber fence along both road frontages is fully compliant (within the triangle at 1.0m, stepping up to 1.2m outside it). It’s not 1.8m, but 1.2m solid can provide meaningful privacy at street level, particularly if combined with planting behind it.
A stepped fence design. The fence is 1.0m in the corner triangle, rises to 1.2m solid (or up to 1.8m permeable) on the road frontage outside the triangle, and continues to 1.8m solid once it reaches the side boundary. This is the most common approach for homeowners who want maximum privacy on the side boundary while complying with the corner rules. Requires careful design at the post layout stage.
A permeable fence at height. On the road frontage portion (outside the triangle), a fence that is entirely visually permeable can go to 1.8m under the NCC permitted rules. This won’t give you solid privacy from the road, but it can create a sense of enclosure and boundary definition at a height that a solid fence couldn’t achieve. Timber batten fencing with deliberate gaps, or a slatted aluminium style, can work here — the rule is that the gaps must be present across the full face of the fence.
Planting to supplement a lower fence. Council rules govern structures. Planting is not a fence and is not subject to the same height restrictions. A 1.0m or 1.2m solid fence in the corner triangle combined with a hedge or screening shrub behind it can achieve the privacy effect of a taller fence without the compliance issue. The planting takes time to establish, but it’s not limited by the splay rules.
What happens if you build outside the rules?
Council can issue a notice requiring you to modify or remove a non-compliant fence. On corner sites, this is more likely than on a mid-block property, because the visibility splay is directly visible from the road and affects other users of the street.
Neighbours and other road users notice corner site fences. The risk of a complaint — and therefore a compliance notice — is real.
More practically: a non-compliant fence on a corner site shows up on a Land Information Memorandum (LIM) report, which is obtained by solicitors in almost every property transaction. A fence flagged as non-compliant on a LIM creates problems at sale time, either requiring remediation before settlement or affecting the negotiated price.
The cost of removing and rebuilding a fence because the splay rule wasn’t followed is considerably more than the cost of getting the design right before the first post goes in.
Tasman District Council — does it have the same rules?
TDC has similar intent around intersection visibility but applies it through different mechanisms and measurements. Properties in Richmond, Brightwater, and other TDC-administered areas should check the Tasman Resource Management Plan rules for corner sites specifically, as the measurements may differ from NCC’s 1.5m/1.0m standard.
The underlying principle is the same — maintain sightlines at intersections for road safety — but the specific setback distances and height thresholds may differ. If your property is in the Tasman district, confirm the specific rules before designing your corner fence.
A quick note on driveway sightlines
Separate from the road-to-road corner splay, both NCC and TDC have rules about sightlines at driveways. Any structure — including fencing — within a defined distance of a driveway exit must not exceed 0.9m in height, to protect pedestrians on the footpath from being hidden from a driver exiting onto the road.
This applies to fences on any property with a vehicle crossing or driveway, not just corner sites. It’s a common surprise for homeowners who want a fence or gate close to the driveway. Ask Kiwi Excavations about this as part of any quote involving a fence near a driveway entry — it’s a detail that affects post placement and gate position.
If you’re on a corner section and want to know exactly what’s achievable before you spend money on a fence, a site assessment is the right place to start. Matt can check the specific rules for your property, walk the boundary with you, and design a fence layout that complies and looks right.

Frequently Asked Questions
What is a visibility splay exactly?
A visibility splay is a triangular area at the corner of a property where road boundaries meet. Nelson City Council requires this triangle to be kept clear of structures above 1.0m in height so that drivers, cyclists, and pedestrians can see each other at the intersection. The triangle is measured by taking 1.5 metres along each road boundary from the corner point — the area between those two measurements and the corner is the splay.
Can I apply for resource consent to build higher in the splay?
Technically yes, but NCC is unlikely to approve a structure that directly compromises intersection sightlines. The visibility splay rule exists for road safety, and consent applications that would reduce sightlines at an active intersection face a high bar. If you have a specific reason why you need height in the splay area, discuss it with NCC’s planning team before applying — they can give an early indication of whether an application is worth pursuing.
Does the splay rule apply to rural or rural-residential properties?
Intersection safety requirements apply across all zones, but the specific measurement and height thresholds may differ in rural or rural-residential areas. Rural roads have different speed environments and sightline requirements from urban streets. Check the relevant district plan rules for your specific zone rather than assuming the residential rules apply.
What if my existing fence in the splay is over 1.0m?
If the fence was there before the current rules, or before you owned the property, it may be a pre-existing non-complying structure. As long as you don’t modify or extend it, a pre-existing non-complying fence is generally tolerated. If you replace it, you’d need to bring it into compliance. If a neighbour or council has raised the issue, take advice on whether you’re required to act on the existing fence.
Does the splay rule apply to gates as well as fences?
Yes. A gate is a structure for planning purposes and is subject to the same height restrictions as fencing within the splay. A gate at the driveway entry that sits within the splay area must be 1.0m or lower in height. If the gate needs to be taller for security or privacy reasons, it should be positioned outside the splay — ideally set back from the road boundary far enough that it clears the triangle entirely.
