New and updated flood maps for four Porirua catchments are open for public feedback, alongside proposed changes to the city’s land-use rules.
The proposals cover Mana, Pukerua Bay, Aotea/Paremata and Whitby’s Duck Creek catchment. They form four of six changes Porirua City Council is proposing to its District Plan, which governs how land can be used across the city.
For Mana and Pukerua Bay, the council proposes updating the flood maps so they use a consistent method with other catchments in Porirua. In Aotea and Paremata, revised modelling would account for changes to the shape of the land caused by recent development.
Whitby’s Duck Creek catchment would receive new flood modelling and mapping using updated land-height information following significant development. The council says the changes are part of planning for flood risks now and in the future.
Plan Changes 1 and 2 deal with corrections and provisions the council says need to work more clearly. They would also update documents referred to in the plan, remove a heritage listing and remove the appendix of approved locations for temporary signs.
Residents can comment on any or all of the six changes. Submissions must include the information required by Form 5 and say whether the submitter wants to speak at a hearing. Copies of the proposals are available at 16 Cobham Court and city libraries.
Submissions, including names and addresses, generally become public. Anyone seeking confidentiality can contact [email protected]. Independent submission help is available from Emily Bayliss on 021 0843 5999 or [email protected].
Submissions close at 5pm on Monday 14 December 2026. They can be lodged through the council’s online submission forms, emailed to [email protected] with “Proposed Plan Changes” in the subject line, or delivered to 16 Cobham Court or a city library.
After submissions close, the council will publish a summary and invite further submissions supporting or opposing those already received. Hearings will follow if submitters ask to be heard, before the council makes its decisions.
