Painting your house is one of the most effective ways to refresh its appearance, protect it from New Zealand’s harsh weather, and increase property value. But one of the most common questions homeowners ask is: how much does it cost to paint a house in NZ?
The answer depends on several factors, including house size, condition, paint quality, and whether you’re painting the interior, exterior, or both. In this guide, we’ll break down realistic costs and help you budget properly.

Key Factors That Affect House Painting Costs
1. Size of the House
The bigger your home, the higher the cost. A small house (100–150m²) may cost under $10,000, while larger homes can exceed $20,000.
2. Interior vs Exterior
Exterior painting is usually more expensive because:
- It requires scaffolding or safety equipment
- It must withstand harsh weather
- More preparation is needed
3. Surface Condition
Older homes often cost more to paint due to:
- Cracks and holes
- Peeling paint
- Moisture or mould damage
Preparation can make up 40–60% of total labour costs.
4. Paint Quality
Higher-quality paints cost more upfront but last longer in NZ’s climate.
- Basic paint: cheaper but less durable
- Premium paint: better UV and moisture resistance
5. Accessibility
If your home is:
- Multi-storey
- On a slope
- Hard to access
Expect additional costs for scaffolding or lifts, which can add $1,500 – $4,000+.
6. Location in NZ
Painting costs vary by region:
- Auckland & Wellington: higher prices
- Smaller towns: slightly cheaper labour
Interior vs Exterior Painting: Cost Comparison
| Type | Average Cost | Notes |
|---|---|---|
| Interior | $5,000 – $15,000 | Depends on rooms & finishes |
| Exterior | $6,000 – $20,000 | Higher due to access & weather |
| Full House | $15,000 – $30,000+ | Best value when combined |
