For a typical 100 m² NZ house, expect to pay $4,000–$8,000 for budget synthetic carpet supplied and installed (including underlay), $10,000–$15,000 for mid-range wool blend, and $20,000+ for premium wool or specialty carpets. Cost per m² supplied and installed: budget synthetic $40–$80, mid-range wool blend $100–$160, premium wool $180–$300+. Quotes usually include uplift of old carpet, smoothedge nailing, and basic installation. Source: Flooring Xtra, Carpet Court.

Broadloom is the standard width of carpet rolls. In NZ, broadloom is 3.66m (12 feet). For rooms wider than 3.66m, you will need a join — carpet installers minimise visible joins by placing them in low-traffic areas. The broadloom width affects wastage: a room of 3.5m × 5m has minimal wastage, but a room of 4m × 5m needs an extra strip with significant offcuts. Always discuss the seam plan with your installer.

NZ wool carpet (often Cavalier Bremworth or Hycraft) is more durable, naturally fire-resistant, breathable, and biodegradable but costs 2–3× more than synthetic. Synthetic carpet (nylon, polypropylene) is more stain-resistant, cheaper, easier to clean, and a good choice for high-traffic areas, rentals, or families with kids/pets. Solution-dyed nylon offers the best stain resistance. Wool blends (e.g. 80/20) offer a middle ground. Source: NZ Wool industry, retailer advice.

Underlay is the foam or rubber pad placed under your carpet — and it can extend the life of your carpet by 30–50%. Quality underlay also improves comfort underfoot, sound insulation, and thermal performance (helps insulate floors in NZ homes that often lack underfloor insulation). Common NZ types: standard PU foam ($8–$15/m²), premium felt or wool blend ($15–$25/m²), and specialty acoustic underlay ($25–$40/m²) for upstairs rooms in apartments. Most installers recommend 8–11mm thickness for residential carpet. Cheap or worn underlay causes the carpet to flatten and wear out years sooner. Always replace underlay when re-carpeting unless the existing underlay is in excellent condition. Source: Carpet Court, Bremworth installation guides.
