Timber vs Composite Deck: The Ultimate Guide for New Zealand Homeowners
When it comes to decking in New Zealand, homeowners often ask: Timber vs composite deck—which is better? Both materials have their benefits, but timber remains the preferred choice for those who value natural beauty, durability, and cost-effectiveness.
Timber vs Composite Decking Cost
One of the first considerations is price. Timber decking is generally cheaper than composite, especially when using locally sourced wood like treated pine or hardwoods. Composite decking materials are made from a mixture of wood fibers and plastic, which increases the cost.
Timber decking cost per square metre in NZ: Typically ranges from NZ$80–$150 depending on wood type.
Composite decking cost per square metre in NZ: Usually between NZ$130–$200.
Conclusion: For budget-conscious homeowners, timber decking is often the more cost-effective option.
Is Composite Decking Cheaper Than Wood in NZ?
Many homeowners wonder: Is it cheaper to build a wood deck or composite deck? The answer depends on upfront vs long-term costs. Timber is cheaper to install, while composite may save on maintenance over the years. However, in New Zealand, the initial cost of composite decking is usually higher than timber.
Durability and Maintenance: Is Composite Better Than Real Wood?
Composite decking is marketed as low-maintenance and resistant to rot, splinters, and insects. While it lasts around 25–30 years, timber can last longer if properly maintained, especially hardwoods like kwila or macrocarpa.
Maintenance:
Timber: Requires annual staining or sealing, but minor scratches can be sanded out.
Composite: Needs occasional cleaning with soap and water or a power washer, but can be slippery in winter.

Safety Considerations: Slipperiness and Weather Resistance
A common concern is: Is composite decking slippery in the winter? Composite decks can become slick when wet, especially cheaper models without anti-slip textures. Timber, while also slick when wet, can be sanded or treated with anti-slip coatings.
Choosing Between Timber and Composite Decking
Here’s a breakdown to help you decide:
Factor: Initial Cost
Timber: Lower
Composite: Higher
Factor: Maintenance
Timber: Annual sealing/staining
Composite: Occasional cleaning
Factor: Lifespan
Timber: 25+ years
Composite: 25–30 years
Factor: Appearance
Timber: Natural, authentic
Composite: Uniform, modern
Factor: Slipperiness
Timber: Can be treated
Composite: May be slippery
Recommendation: For most NZ homeowners, timber decking offers the best balance of cost, aesthetics, and longevity.
