Proposed Plan Change 18 Plimmerton Farm

Porirua City Council has prepared Proposed Plan Change 18: Plimmerton Farm to the Porirua City District Plan (Plan Change 18). 

Plan Change 18 seeks to rezone the property known as Plimmerton Farm (Lot 2 DP 489799) from Rural Zone to a new Plimmerton Farm Zone. The new zone is intended to provide for urban development including housing, a retirement village, a commercial area, water sensitive design to protect sensitive receiving waters and protection and augmentation of Significant Natural Areas, including wetlands that form part of the Taupō Swamp Complex. Specific changes are also proposed to City-wide provisions of the District Plan to apply to the proposed Plimmerton Farm Zone.

Streamlined Planning Process

Proposed Plan Change 18 Plimmerton Farm is proceeding through a Streamlined Planning Process. The process is set out in the Minister for the Environment’s Direction for the Streamlined Planning Process, which was gazetted on 6 May 2020.

Here is a summary of the process. The steps and timeframes will be updated as the process moves forward.

Submissions – Plan Change 18 was publicly notified on 20 May 2020. Submissions closed on 2 July 2020.

Further Submissions – The Summary of Decisions Requested (Summary of Submissions) was publicly notified on 14 July 2020. Further submissions closed on 28 July 2020. Further submissions support or oppose original submissions.

The Hearing before the independent Hearing Panel (see membership below) will begin on 12 October 2020. Submitters have the opportunity to speak and present expert evidence in support of their submissions.

Hearing Panel Minute 1 sets out how the hearing process will be managed to ensure clarity and certainty for all parties and a fair and efficient hearing process. Minute 1 provides a timetable and directions to Council on providing the Council report to the Hearing and to submitters on providing any lay or expert evidence they wish to provide as well as instructions on participating in pre-hearing meetings and expert conferencing. 

Please note that all correspondence for the Hearing Panel must be via the Hearing Administrator Maria Joslin (, phone 04 237 3863). 

After the Hearing, the Hearing Panel will issue a draft recommendation to submitters and Council, giving the opportunity for correction of minor or technical errors. The draft recommendation is likely to take several weeks to prepare.

The Hearing Panel then issues its recommended decision to the Minister for the Environment.

The Minister will then make the final decision on the plan change.
