Iwi groups are proposing renaming the Hutt Valley suburb Petone as Pito-one.

The bid to change the spelling and pronunciation is going before the City Council tomorrow, before eventually being seen by the Geographic Board.

Pito-one is the original name, which was switched by colonial settlers.

Palmerston North Maori Reserve Trust Chair Liz Mellish says many places in the area already use the old spelling.

"There seems to be a real feeling in the community, we've got an apartment called Pito-one, we've got a café, we've got a football club."
