Estimate a New Zealand house's 2026/27 council rates and water charges.
Use for: 'how much are rates on a $700k house', 'council rates calculator
nz', 'auckland rates estimate', 'christchurch rates and water', 'what are
water rates in wellington', 'rates per week nz'.
ONLY NINE COUNCILS, each for a standard house in the area stated:
Auckland (Watercare-metered house), Wellington City, Christchurch City,
Hamilton City, Tauranga City, Dunedin City, Selwyn (Rolleston),
Waimakariri (Rangiora) and Queenstown Lakes (Queenstown). Any other council
or town (Kaiapoi, Wanaka, Upper Hutt, Nelson...) returns an error: tell the
user to use that council's own rates search. Never substitute another
council's figures.
FIGURES ARE EACH COUNCIL'S ADOPTED 2026/27 RATES, GST inclusive, with the
water organisation's 2026/27 prices where it bills water (Watercare, Tiaki
Wai, IAWAI, Selwyn Water). Usage matters only in Auckland, Tauranga,
Selwyn, and Christchurch above 900 litres a day (each part of a m3 charged
as a whole one). A usage of 0 is 0; null is the 170 m3 starting figure.
For Waimakariri pass land_value, or its urban drainage rate is left out
(land_value_rate_left_out says so).
Outside Auckland (a unitary council) regional council rates are NOT
included. Every answer carries source_url, rating_year and not_included.
Args:
capital_value: The property's capital value in dollars.
council: A council key or name from the page.
water_usage_m3: Annual water use in cubic metres. Default 170.
land_value: The property's land value; used only for Waimakariri.
Returns:
General rate, UAGC, water, wastewater, stormwater, rubbish, other
targeted rates, the total yearly, quarterly, monthly and weekly, rates
as a share of CV, who bills water, the 2026/27 rebate figures, the
rating year and the council's source.
