For trailers & semi-trailers

Parts for trailers and semi-trailers in New Zealand

Updated 31 October 2026

Trailer and semi-trailer parts in New Zealand cost from about NZ$6 for an amber marker light to around NZ$1,070 for a truck or trailer tyre, and a tandem axle kit for a 3500kg trailer is roughly NZ$7,400 to NZ$8,000. For a price on the exact part you need, describe it on BlaBlaPrice, and the AI looks through local sellers' websites and price lists for current prices.

Legal limits and what to check

Heavy trailers and vehicle combinations must meet the dimension and mass limits in the Land Transport Rule: Vehicle Dimensions and Mass 2016. Give the trailer's GVM (gross vehicle mass) in kilograms and its axle rating before you buy a wheel, axle or brake part. Heavy trailers over 3500kg are treated differently from light trailers, so state the weight class in your request. For semi-trailers, towing connections must carry NZ Certification under the Heavy Vehicle Rule, so ask the seller to confirm this in writing.

Warranty and consumer rights

For goods bought in New Zealand you usually do not need an extended or manufacturer's warranty, because consumer law already protects you, unless the seller's warranty offers more than that. Still, ask for the warranty terms in writing, especially for brakes and axles, and check what happens if a part arrives faulty.

Winter, delivery and how parts are bought

Winter runs from June to August, and lights get more use in the dark evenings, so it is a good time to check marker and tail lights before the cold months. Summer runs December to February. Ask whether a price includes GST, since New Zealand prices are sometimes quoted without it. Delivery is usually to your address or a freight depot, so give your city, which may be Auckland, Wellington, Christchurch, Hamilton or Tauranga, and check whether freight is included.

What to put in your request

Name the part and the trailer type, such as a flatdeck, a tandem or a semi-trailer. Give the trailer model, the year and its specifications, and the part number if you have it. Say whether you want original or compatible parts, and the condition you need the part in. Add the delivery city and your budget. Metric measurements such as millimetres, kilograms and tyre sizes like 385/55R22.5 make offers easier to compare.
