Gate and fence welding jobs in New Zealand vary widely in how long they take — a simple repair might be done in an hour or two, while a full custom driveway gate installation could take a full day or more. The timeline depends on the size of the job, the materials involved, site conditions, and whether any fabrication needs to happen off-site first. Here's what you can expect.
Typical Timeframes at a Glance
The table below gives a rough guide to how long common gate and fence welding jobs take. These are approximate figures — your tradesperson can give you a more accurate estimate once they've assessed the site.
| Job Type | Approximate Time |
|---|---|
| Small weld repair (broken hinge, cracked rail) | 1–3 hours |
| Single pedestrian gate installation | 2–4 hours |
| Double driveway gate installation (pre-fabricated) | 4–8 hours |
| Custom fabricated driveway gate (design + build) | 1–3 days |
| Fence panel welding (per panel, on-site) | 1–2 hours per panel |
| Full boundary fence (multiple panels, posts, gates) | 2–5 days or more |
These timeframes cover the welding and installation work itself. They don't always include time for surface preparation, priming, or painting, which adds to the overall project duration.
What Affects How Long the Job Takes?
Several factors can speed up or slow down a gate or fence welding job:
Material Type
Mild steel is the most common material for NZ gates and fences and is straightforward to weld. Stainless steel requires more care and specialist technique to avoid contamination and discolouration. Aluminium welding (TIG welding) is more time-consuming and requires a skilled operator. Each material has different prep, heat management, and finishing requirements.
Fabrication vs. Installation
If your gate is being custom fabricated — designed and built from scratch — most of the work happens in the welder's workshop before they arrive on-site. Workshop fabrication for a large driveway gate can take a full day or more on its own. If you're buying a pre-fabricated gate from a supplier and just need it hung and welded into place, the on-site time is much shorter.
Site Conditions
Working on a sloped section, uneven ground, or a site with limited access can add time. Posts that need to be set in concrete require the concrete to cure (typically 24–48 hours) before the gate can be hung and adjusted properly.
Finishing Work
Welded steel needs to be ground smooth, then primed and painted or powder-coated to protect against NZ's weather — especially in coastal areas where salt air accelerates rust. Painting on-site adds time; powder-coating is usually done off-site at a specialist facility and can add a few days to the overall timeline.
Automation and Hardware
Automated gate systems (electric openers, intercoms, keypad entry) add complexity. The electrical wiring for gate motors is restricted electrical work and must be carried out by a registered electrician — see the Electrical Workers Registration Board (EWRB) for more information. Your welder may coordinate with an electrician, which can affect scheduling.
Does the Job Need a Building Consent?
In New Zealand, some fence and gate structures require a building consent from your local council. Under Schedule 1 of the Building Act, certain low fences are exempt, but height limits and proximity to boundaries matter. Retaining walls and fences over certain heights generally do require consent. Always check with your local council before starting work — requirements vary by region and district plan. The MBIE Building Performance website is a good starting point for understanding the rules.
Protecting Your Steelwork in NZ Conditions
New Zealand's climate — particularly in coastal and high-humidity areas — can be tough on steel. A good welder will recommend appropriate primer and topcoat systems to extend the life of your gate or fence. Brands like Resene and Dulux offer metal primer and enamel systems suited to NZ conditions. For technical guidance on corrosion protection, BRANZ publishes useful research relevant to NZ building and construction.
When to Call a Professional
Welding is a skilled trade requiring proper equipment, training, and safety knowledge. Structural welding — including gate posts, hinges carrying significant loads, and any welding that forms part of a building structure — should always be carried out by a qualified and experienced welder. Attempting DIY welding without proper training risks poor-quality joins that can fail, as well as serious safety hazards including fire, UV eye damage, and fume inhalation. WorkSafe NZ has guidance on welding hazards and safe work practices.
As noted above, any electrical work associated with automated gates must be done by a registered electrician.
