Paving in NZ — What to Budget

Paving costs vary widely depending on material choice and access. A standard concrete paver driveway is one of the most cost-effective options; natural stone adds significant expense.

Paver Costs by Type (NZ, 2025)

Paver type Material cost (m²) Installed (m²)
Concrete pavers (plain) $30–$60 $110–$160
Brick / clay pavers $55–$95 $140–$200
Natural stone (bluestone etc) $90–$180 $200–$320
Porcelain tiles (outdoor) $70–$140 $170–$260

Base Course Requirements

Correct base preparation is critical — poor base = sunken, cracked pavers within 2–3 years: - Pedestrian paths: 75mm AP20 compacted - Driveways (cars): 100–150mm AP20 compacted - Driveways (trucks/heavy): 150–200mm AP20 + geotextile

Drainage

Always design paving to drain away from the house at minimum 1:100 fall (10mm per metre). Poor drainage is the #1 cause of paving failures.
