How rates are decided

The rates you pay for the coming year are decided as part of the Long-term Plan and Annual Plan process.

How rates are decided

As part of preparing for each Long-term Plan or Annual Plan, we ask for your views about the spending we’re planning and the amount we may need to charge ratepayers. The rates payable in the coming year are decided at the end of this process.

All property owners pay rates, including government departments and Kāinga Ora – Homes and Communities. You can read about each year’s spending outcomes in our Long-term Plan.

Our rates must meet the requirements of the Local Government (Rating) Act 2002. Non-rateable land and 50% rateable land are defined in Schedule 1 of the Act.

How property valuations affect rates

Our independent contractor Quotable Value carries out property valuations for Porirua City every three years. Quotable Value works out the value of your property by looking at the selling price of similar properties in the area. The last revaluation was based on property values as at 1 October 2022. 

You can use the Property Search to see the final values.

If you think of rates as a pie, the size of the pie doesn’t get bigger because of the new valuations. However, a ratepayer’s slice of the pie might get bigger or smaller depending on how their property value has changed in relation to the average change of valuations in the city. The total amount of rates collected stays the same.

This will be updated with information about rates for 2024/25 after the rates are set on 27 June 2024.

Key facts about rates 2025/26

If you are looking at your rates invoice from Porirua City Council it will be calculated with the Porirua City Council rates increase and the Greater Wellington Regional Council (GWRC) rates increase. These are outlined below:

Porirua City Council rates increase

As a Porirua ratepayer, you will have recently received your rates invoice for the 2025/26 year. The Porirua City Council rates increased by (on average) 6.39%. The Annual Plan for 2025/26 has more details. It can be found here

However, the rates increase is not the same percentage for everyone. The actual calculation depends on property type (eg residential, commercial, rural) and the capital value of that property.

Greater Wellington Regional Council rates increase

Included in the rates invoice are the GWRC rates.

Porirua City Council collects those rates on behalf of GWRC. Their Annual Plan can be found here

GWRC also has a Porirua-specific fact sheet here

Their rates increase for residential properties 25/26 was 11.6%.

Comparisons with previous years
If comparing from year to year, it is best done based on the assessment for each Council that was included with the invoice.
