Powder coating & sandblasting

Powder coating and sandblasting in New Zealand: prices and prep

Updated 5 November 2026

Approximately, according to sellers' websites, November 2026, sandblasting in New Zealand costs NZ$22 to NZ$30 per square metre, depending on whether the surface only needs cleaning or paint, rust or old coatings must come off. Powder coating is priced with a minimum charge per colour coat, so the total depends on the size and number of parts. Describe your parts in a request on BlaBlaPrice to get a figure for your own job.

Blasting is quoted per square metre, while labour and the coating minimum are plus GST. Ask for the total including GST before you compare offers.

Surface preparation drives the price

Preparation changes the price. Light cleaning costs less per square metre than heavy removal of paint, rust or old coatings, so describe the surface honestly. Some workshops offer sandblasting and powder coating in-house as a one-stop service for steel, aluminium and stainless steel, which saves moving parts between two places. Ask whether the price includes masking of threads and fittings.

Workshop rules and safety

Blasting and coating use abrasive dust and chemicals, and New Zealand sets rules for hazardous substances in the Health and Safety at Work (Hazardous Substances) Regulations 2017. Ask how the workshop handles dust and chemicals, and whether it holds the licences its process needs.

Timing and the summer months

Summer runs December to February and winter June to August. Your request is for November, so a summer deadline is realistic only if a workshop has a free slot. Outdoor blasting depends on the weather, so ask whether the work is done indoors or on an open yard, and tell sellers your deadline early.

How the work is priced and moved

Sellers quote per square metre, per hour or as a minimum per colour coat, so give sizes and quantities in metric units: millimetres and square metres. Ask whether the workshop collects and returns parts between Auckland, Wellington, Christchurch, Hamilton or Tauranga, or whether you drop them off yourself.

What to write in your request

List what needs treating and the machining type, the size or area of each part, and how many pieces there are. Describe the surface condition, the colour (give the RAL number if you have one), whether parts must be dismantled, your deadline, your city and your budget. A photo helps sellers see the rust and the shape.

Get offers through BlaBlaPrice: describe the parts, sizes, colour and deadline in the request field on the home page. BlaBlaPrice's AI reads the request, asks for missing details and looks through local sellers' websites and price lists, then shows the prices and businesses it found. Registered workshops reply in the chat with their own offer, and your contacts stay hidden until you decide whom to contact.
