Artificial turf in New Zealand typically runs between $70 and $130 per square metre, supplied and installed. The final price hinges on the level of base preparation required and the quality of the synthetic grass you choose. This guide walks you through the numbers and what influences them.

The table shows how total spend scales with both size and the amount of groundwork needed, staying within the $70‑$130 /m² range.
Factors that affect the price
Base preparation – Removing existing grass, leveling, and adding a compacted stone base are the biggest cost drivers; a well‑drained, compacted base can keep you at the lower end of the range. Turf quality – Higher‑density fibres and UV‑stable backing increase durability but push the per‑metre price toward $130. Drainage solutions – In regions with heavy rain, a perforated sub‑base or integrated drainage mat adds material and labour costs. Site access and slope – Tight access or steep grades require extra labour and specialised equipment, nudging the price upward. Size of the job – Larger installations benefit from economies of scale, often allowing a mid‑range $100‑$110 per m² rate.
DIY vs professional installation and consent requirements
A confident DIYer can lay artificial turf on a flat, well‑prepared surface for a modest project, but professional installation ensures the base is correctly compacted and drainage is integrated – critical for NZ’s variable climate. Building consent is rarely needed for a simple turf overlay, but if you alter the existing drainage or raise the ground level, you must check the local council’s Building Act requirements. WorkSafe expects any subcontractors handling heavy machinery to be trained and insured, so hiring a licensed installer protects you from liability. For most homeowners, the peace of mind and warranty support from a reputable tradie outweigh the modest savings of a DIY approach.
Regional price variations and drainage for NZ climate
Northland and Auckland see higher labour rates, so expect totals toward the $120‑$130 /m² end, especially where sand‑based bases are common. In the South Island, lower labour costs can bring the average to $80‑$100 /m², but colder, wetter winters demand more robust drainage, sometimes adding a $5‑$10 /m² surcharge for perforated sub‑bases. Coastal areas may require anti‑mould treatments, while inland regions with lighter soils often need a thicker stone layer. Always factor local rainfall patterns – a well‑designed drainage system can prevent water pooling and extend the life of your synthetic lawn.
