From this page on the KCDC website:

Check your proposed rates

Interested to know what your property rates might be next year?  The Council is currently working through our long term planning process that will set your rates, along with our work programme, for the coming year.

So, while your actual rates for 2018/19 won’t be confirmed until the final long term plan is adopted, we can let you know what the proposed plan, and your recent property revaluation, will mean for your rates.

You’ll see that there are four different adjustments that together add up to the total proposed change to your rates bill for the 2018/19 year, which begins on 1 July 2018.  The adjustments are for:

  1. The impact of your 2017 property revaluation
  2. A change that the Kāpiti Coast District Council (KCDC) is proposing to make to the way we share rates across the district
  3. KCDC’s proposed rates increase for 2018/19
  4. Greater Wellington Regional Council’s (GWRC’s) proposed rates change.

The page enables you to plug in your property valuation number (via the property register) to see what your increase will be.

We’ve done that for a few in our neighbourhood and 9.4% seems to be the typical increase.

The KCDC says it wants ratepayers to let them know what they think, and we recommend you do: the page containing the long term plan consultation pdf and your submission on it is here.

Submissions close at 5 pm on Monday 23 April 2018.
