Choosing between natural turf and artificial turf is one of the most common decisions NZ homeowners face when landscaping or renovating their outdoor spaces. Both options have genuine merits — and real drawbacks — depending on your lifestyle, budget, climate, and how you use your lawn. This guide gives you an honest, practical comparison so you can make the right call for your property.
Overview: Natural Turf
Natural turf — whether laid as instant turf or grown from seed — is a living lawn made up of grass species suited to your region. Popular NZ varieties include Sir Walter Buffalo, Kikuyu, RTF Tall Fescue, and Couch, each suited to different climates and uses. New Zealand's varied climate means grass choice matters: a shade-tolerant fescue blend suits a Dunedin garden far better than a warm-season Kikuyu, which thrives in Northland or the Waikato.
Natural turf provides genuine environmental benefits — it absorbs rainwater, reduces urban heat, supports soil biology, and sequesters carbon. It also feels and looks unmistakably real, which many homeowners value. The trade-off is ongoing maintenance: mowing, fertilising, watering, aerating, and weed control are all part of the deal.
Overview: Artificial Turf
Artificial turf (also called synthetic grass or fake grass) is a manufactured surface made from polyethylene or polypropylene fibres, typically infilled with crumb rubber, sand, or organic materials. Quality varies enormously — budget products can look plastic and wear quickly, while premium products can be convincingly realistic and last many years.
Artificial turf has surged in popularity across NZ, particularly in urban areas where water restrictions, small sections, or high-traffic zones make maintaining a natural lawn difficult. It's especially common in Auckland, Wellington, and Canterbury where dry summers or heavy shade create challenging growing conditions. However, it comes with its own set of considerations around heat retention, environmental impact, and eventual disposal.
Head-to-Head Comparison
| Criteria | Natural Turf | Artificial Turf |
|---|---|---|
| Upfront cost (guide only) | Lower to moderate (turf + prep) | Higher (materials + installation) |
| Ongoing maintenance | Regular — mowing, watering, fertilising | Minimal — occasional brushing, rinsing |
| Durability | Can thin or die in heavy traffic or drought | Handles heavy traffic well; UV degradation over time |
| Appearance | Lush and natural; seasonal variation | Consistent year-round; quality varies by product |
| Heat in summer | Stays relatively cool | Can get very hot in direct NZ sun |
| Water use | Moderate to high, especially in dry summers | Near zero once installed |
| Environmental impact | Positive (carbon, biodiversity, drainage) | Negative (plastic waste, heat island, drainage issues) |
| Pet & child safety | Natural and safe; mud possible | Hygienic if maintained; heat risk in summer |
| DIY suitability | Moderate — turf laying is achievable | Difficult — sub-base prep is critical |
| Lifespan | Indefinite if maintained | Typically 10–20 years before replacement |
| End of life | Biodegrades naturally | Difficult to recycle; goes to landfill |
Cost Considerations
As a rough guide only, natural turf is generally the more affordable option upfront — instant turf plus ground preparation is typically less expensive per square metre than a quality artificial turf installation. However, factor in the ongoing costs of water, fertiliser, lawn care products, and your time (or a lawn mowing service) over the years.
Artificial turf has a higher upfront cost, largely driven by the sub-base preparation (compacted aggregate, weed mat, edging) and the turf itself. Cheaper products may save money initially but can look poor and degrade faster — it's worth investing in a quality product from a reputable NZ supplier. Over a 10–15 year period, costs can be comparable once you account for natural turf maintenance.

NZ Climate and Environmental Factors
NZ's climate is diverse, and this significantly affects which option performs best. In regions with water restrictions (common in Canterbury, Hawke's Bay, and parts of Auckland during summer), maintaining a natural lawn can be genuinely difficult and expensive. Artificial turf removes that pressure entirely.
However, artificial turf's heat retention is a real concern in NZ's increasingly warm summers. Synthetic surfaces can reach temperatures well above air temperature on sunny days — a significant issue for children and pets. Natural grass stays considerably cooler.
From an environmental standpoint, BRANZ and other building and sustainability researchers highlight that natural turf contributes to stormwater absorption and urban cooling — both increasingly important as NZ cities face climate adaptation challenges. Artificial turf, by contrast, typically requires a drainage layer but does not absorb water the same way, and the plastic fibres contribute to microplastic pollution over time.
Maintenance: What's Actually Involved
Natural turf maintenance
- Mowing every 1–2 weeks in the growing season
- Fertilising 2–4 times per year
- Watering during dry spells
- Aerating and dethatching annually
- Spot-treating weeds and pests
Artificial turf maintenance
- Brushing fibres upright every few months
- Rinsing off pet waste, dust, and debris
- Checking and clearing drainage points
- Occasional infill top-up
If you have pets, artificial turf requires diligent rinsing to prevent odour build-up — this is a commonly underestimated maintenance task.
DIY or Hire a Pro?
Laying instant turf is a manageable DIY project for a reasonably capable homeowner — ground preparation, levelling, and laying rolls are all achievable with the right tools. Mitre 10 and Bunnings stock turf preparation products, fertilisers, and tools.
Artificial turf installation, however, is best left to professionals. The sub-base preparation is critical — poor compaction or drainage leads to uneven surfaces, pooling water, and premature wear. A qualified landscaper will also ensure correct edging, joins, and infill for a long-lasting result.
Note: if your landscaping project involves irrigation systems connected to your home's water supply, this may involve restricted plumbing work requiring a licensed tradesperson registered with the Plumbers, Gasfitters and Drainlayers Board.
Our Recommendation
There's no single right answer — it depends on your situation:
-
Choose natural turf if you value environmental benefits, have children or pets who play on the lawn regularly, live in a region with reliable rainfall, and don't mind the ongoing maintenance. It's the better long-term choice for most larger sections.
-
Choose artificial turf if you have a small, high-traffic area (like a courtyard or play zone), face severe water restrictions, have a heavily shaded area where grass won't grow, or genuinely cannot commit to lawn maintenance. Invest in a quality product and have it professionally installed.
-
Consider a hybrid approach — many NZ homeowners use artificial turf in specific zones (under a trampoline, along a side passage, in a shaded corner) while maintaining natural turf elsewhere. This balances practicality with environmental responsibility.
Whatever you decide, getting advice from an experienced local landscaper is well worth it. Find qualified landscapers in your area at tradedirectory.co.nz.
