Some Pacific local body politicians in Wellington say a supercity would leave their communities worse off.
Pacific people make up about 8% of the Greater Wellington population but have only four councillors - three in Porirua and one in Hutt City.
Public consultation on proposals for a single council for the region ended on Friday.
Porirua City councillor Wayne Poutoa says a single council would mean even fewer Pacific representatives, and less attention to the needs of Pacific communities.
A deputy chair of the Wellington City Council's Pacific advisory group, Anthony Leaupepe, says the solution is a Pacific voting ward for greater Wellington.
But long-serving Porirua councillor Litea Ah Hoi says Porirua has shown it can elect Pacific councillors and should be able to do it for a single regional council.
