Choosing a patio surface is one of the most impactful decisions you'll make for your outdoor living space. Get it right and you'll enjoy it for decades; get it wrong and you're looking at costly repairs or a redo within a few years. In New Zealand, our varied climate — from Auckland's humidity to Otago's frosts — means the choice really does matter. Here's an honest, practical breakdown of the three most popular options: pavers, poured concrete, and timber or composite decking.
Overview of Each Option
Pavers
Pavers are individual units — typically concrete, clay brick, or natural stone — laid on a compacted base with sand or mortar. They're enormously popular in NZ because they suit our outdoor lifestyle and come in a huge range of styles. Brands like Firth and Adbri offer a wide selection through Mitre 10 and Bunnings. Pavers can be DIY-friendly for smaller areas, though a proper compacted sub-base is critical — skip this step and you'll have a wobbly, uneven surface within a season or two.
Poured Concrete
Poured (or "slab") concrete is a single continuous surface formed in place. It's the workhorse of NZ patios — strong, long-lasting, and relatively low maintenance once sealed. It can be finished in many ways: plain grey, exposed aggregate, broom-finished, or stamped to mimic stone. Concrete is almost always a job for a professional, as getting the mix, reinforcing, and drainage fall right requires experience. BRANZ research consistently highlights poor drainage as the leading cause of patio and path failures in NZ.
Timber and Composite Decking
Decking — whether treated pine, hardwood (like kwila or vitex), or composite (timber-plastic blend) — creates a warm, natural feel that many Kiwis love. It's the go-to solution for sloped sections where a ground-level slab isn't practical. Treated pine is the budget-friendly entry point; composite products like those from James Hardie or brands such as Futurewood offer lower maintenance and longer life. Structural decking work (framing, posts, bearers) must comply with NZS 3604 and, if over 1.5 m above ground, may require a building consent from your local council — check with MBIE Building Performance before you start.
Head-to-Head Comparison
| Criteria | Pavers | Concrete | Decking |
|---|---|---|---|
| Approx. installed cost | Mid–high | Low–mid | Mid–high |
| Durability | 20–40+ yrs (individual units replaceable) | 25–40+ yrs (can crack) | 15–25 yrs timber; 25+ yrs composite |
| Appearance | Versatile, traditional to modern | Plain to decorative; can look utilitarian | Warm, natural; suits NZ indoor-outdoor flow |
| Maintenance | Re-sand joints every few years; seal stone | Reseal every few years; patch cracks | Oil/stain timber annually; composite low-maintenance |
| Slip resistance | Good (textured surface) | Moderate (seal carefully) | Moderate (can be slippery when wet) |
| Frost/heat suitability | Good (movement absorbed by joints) | Can crack in freeze-thaw zones | Good (timber moves naturally) |
| Drainage | Excellent (permeable joints) | Requires careful grading | Excellent (gaps between boards) |
| DIY friendliness | Moderate | Low (specialist work) | Moderate (framing is complex) |
| Consent required? | Usually no | Usually no | Sometimes (height/size dependent) |
Cost Considerations
As a rough guide only, poured concrete tends to be the most affordable installed option per square metre, making it attractive for large areas. Pavers sit in the mid-to-high range depending on the material — natural stone (schist, bluestone) costs considerably more than concrete pavers. Decking costs vary widely: treated pine is relatively affordable, while hardwood and quality composite products are a premium investment.
Don't forget to factor in:
- Sub-base preparation (excavation, compaction, drainage) — often the biggest hidden cost
- Sealing and finishing products (check Resene or Wattyl for exterior timber and concrete sealers)
- Ongoing maintenance costs over the life of the surface
- Building consent fees if applicable

NZ-Specific Conditions to Consider
Frost zones (Central Otago, Manawatū, parts of Canterbury): Concrete can suffer from freeze-thaw cracking if not properly mixed and reinforced. Pavers handle movement better due to their jointed nature. Timber decking also copes well.
High humidity and rainfall (Northland, West Coast): Timber decking needs diligent maintenance to prevent rot and mould. Composite decking or pavers are lower-risk choices. Ensure all surfaces drain away from the house to comply with the NZ Building Code's E1 (surface water) requirements.
Coastal environments: Salt air accelerates corrosion of fixings and can degrade some sealers quickly. Use stainless steel fixings for decking and choose pavers or concrete with appropriate sealers rated for coastal use.
Sloped sections: Decking is often the most practical and cost-effective solution on a steep slope, avoiding the significant earthworks needed for a level concrete or paver pad.
Safety Note
If your decking project involves any electrical work (outdoor lighting, power points), this is restricted work that must be carried out by a registered electrician — see the Electrical Workers Registration Board for details. Similarly, any outdoor gas connections must be handled by a licensed gasfitter registered with the Plumbers Gasfitters & Drainlayers Board. Structural decking work on larger or elevated decks should involve a Licensed Building Practitioner.
Our Recommendation
There's no single "best" option — it depends on your site, budget, and lifestyle. Here's practical guidance for common NZ scenarios:
- Best for a flat, low-maintenance family patio: Concrete (exposed aggregate or stamped) gives you a durable, easy-care surface at a reasonable cost. Seal it well and it'll last decades.
- Best for a stylish, flexible finish: Pavers offer the most design flexibility and the ability to replace individual units if damaged. Ideal if you want a premium look or may need to access services underneath.
- Best for a sloped section or indoor-outdoor flow: Decking is hard to beat. Choose composite if you want minimal upkeep; treated pine if budget is tight and you're happy to oil it regularly.
- Best for frost-prone areas: Pavers or decking — both handle ground movement better than a solid concrete slab.
- Best for coastal sections: Pavers or composite decking with stainless fixings — both resist the salt environment better than untreated timber.
Whatever you choose, invest in proper ground preparation and drainage — this is where most patio failures begin. A good landscaper will assess your soil, drainage, and slope before recommending a surface. Find a qualified local landscaper on tradedirectory.co.nz to get the job done right.
