Values are calculated by mass valuation of properties. Mass valuation means using standard methods to calculate the values of many properties at once, rather than valuing each one individually. This is done by using recent property and sales information.
To calculate the 2024 property values, valuers looked at the sale prices of similar properties in the same area around 1 May 2024. For example, renovated villas in Grey Lynn were compared with other renovated villas nearby.
Similar residential properties in the same area are likely to have similar value changes. However, the change will vary between standalone houses, cross-leases, units and other types of homes.
Independent property valuers work with the council to set property values. The Valuer-General checks these values to make sure they are correct.
