Assumptions behind this estimate
- Rates are per m² of effective floor area in NZD, including VAT and builder's margin.
- Effective area = floor area + 50% of covered veranda/deck area.
- Two-storey construction carries a 7% structural premium.
- Assumes a buildable, serviced site on Rarotonga with normal ground conditions.
- Excludes land, site retaining, seawalls, water tanks beyond standard, and landscaping.
- Stage shares are typical for residential construction and may shift with design.
This is an indicative estimate for early planning and loan pre-qualification. It is not a fixed quote. Final cost depends on your site, design, and material prices at the time of construction. Estimates are valid for 60 days.
