A quality exterior repaint on a New Zealand home typically lasts 7–10 years, and often longer on sheltered surfaces — but coastal, sun-exposed or poorly prepared surfaces can fail in half that time. Preparation and paint quality make far more difference to lifespan than colour or brand alone.
Typical lifespan by exposure
Not all of a house ages at the same rate. Sheltered south and east walls hold their paint the longest, while north and west faces take the full sun and fade fastest. Coastal homes near Raglan wear quicker again because salt air is so aggressive on coatings. Near-horizontal surfaces like sills and ledges, which pool water and take direct sun, are usually the first to fail.
What makes paint last longer
Preparation comes first — paint can only last if it's bonded to a sound, clean surface. After that it's the grade of paint (premium flexible acrylics hold colour and protect for years longer), the correct number of coats, the right primer, and painting in suitable dry conditions so the coating cures properly. Cut corners on prep or use budget paint and you can halve the life of the job.
Getting the most from your next repaint
Don't wait until timber is bare and greying — repaint while the old coating is fading rather than failing, and it's a smaller job. Wash the exterior periodically, touch up any early failures, and invest in a premium system so you repaint less often over the life of the home.

Frequently asked questions
Does more expensive paint really last longer?
Generally yes, when the preparation is done right. Premium exterior coatings hold their colour and protect the surface for years longer, which usually makes them cheaper over the life of the home.
Why did my last paint job fail so fast?
Early failure almost always comes down to poor preparation, budget paint, or painting over an already-failing coating rather than removing it first.
How often should I repaint then?
Most New Zealand homes need an exterior repaint every 7–10 years, sooner on exposed or coastal sites — see our guide on how often to paint your house exterior.
