Do you need to know more about rating valuations and valuation service providers?

The government services team from Opteon, formerly Landmass Technology, are New Zealand’s quality driven and client focused rating valuation specialists.

Opteon works with local authorities to provide rating valuations on all types of properties. These rateable values (RVs) are used to allocate the total rates levied by local authorities (city or district councils) across all properties in the region. Opteon also consults to Councils on a wide range of property matters.

As a property owner and ratepayer, you need to have confidence that rating valuations on the District Valuation Roll (DVR) provide a fair basis for determining rates. The DVR provides public access to rating valuation information, and the supporting registers provide the Valuer-General with the necessary information to monitor and audit the valuation system for fairness, consistency, and equity. This rating valuation information is also available to the public through their local authority website.
