As the valuation service provider for the Hamilton City Council, Opteon is undertaking a general revaluation for the district this year. New valuation notices will be issued in early 2022 with the effective date of the new valuations being 1 September 2021.

Opteon will be completing property inspections on those which have recently sold and where significant building work has been undertaken. The valuation fieldwork will be undertaken between July and December 2021.

To ensure that the revaluation program is undertaken as accurately as possible, we are requesting property owners of commercial, industrial, accommodation and childcare centers to fill out the revaluation questionnaires accessed via the link below. In the past, you will have received these via post, however given the impacts of COVID-19 we have converted these into a web based platform to minimise contact and ensure ease of return. We encourage all property owners to fill out and return these questionnaires to ensure that Opteon has up to date and accurate information regarding your property. This information will assist in the determination of value and assess any impact that COVID-19 may have had on your property’s value.

More specifically, any information relating to change in rentals, vacancy rates, leases or any other factors that you consider to impact the value of your business and property is considered extremely relevant.

This information is requested under authority of the Rating Valuations Act 1998, Section 45.  Any information you provide is subject to the Official Information Act and the Privacy Act and, therefore, is confidential to Opteon for the sole purpose of assessing the rating values. No individual property data will be provided to any third party.
