House painting in New Zealand typically ranges from a few thousand dollars for a single room or small interior, up to $10,000–$25,000+ for a full exterior repaint of a larger home. The final price depends on size, condition, access, the number of coats and the quality of paint — so the only truly accurate number is a free on-site quote.
What you can expect to pay
As a rough guide, interior repaints often fall between $40–$60 per square metre of wall area, while a full exterior repaint of an average three-bedroom home commonly lands somewhere between $8,000 and $18,000. Roof painting is usually quoted separately and depends heavily on roof type, pitch and condition.
These are ballpark figures only. Two homes the same size can cost very differently to paint depending on how much preparation and repair the surfaces need.
What affects the price most
Preparation is the single biggest variable. Washing, scraping, sanding, filling, priming and repairing damaged surfaces takes time — and it's also what makes a paint job last. Skimping on prep is how cheap quotes stay cheap, and why they fail early.
Other big factors are the size and number of storeys (which affect access and scaffolding), the condition of the existing paint, the number of coats required, and the grade of paint you choose. Premium paints cost more up front but last significantly longer.
Why a fixed quote beats a per-hour estimate
A good painter will visit, assess the actual condition of your home and give you a written, fixed quote for the scope of work. That protects you from surprises and makes it easy to compare like-for-like. Be cautious of quotes that seem far below the others — they often leave out preparation or use cheaper paint.
Frequently asked questions
Is it cheaper to paint inside or outside?
Interior painting is usually cheaper per square metre because there's less preparation and no weatherproofing or access equipment, but a whole-home interior can still add up depending on detail and the number of rooms.
How long does a house repaint last?
With quality preparation and premium coatings, an exterior repaint typically lasts 7–10+ years and interiors longer, depending on exposure and wear.
