Ngāti Whātua Ōrākei is calling for Aucklanders to recognise the 18th of September 1840 as the city's true founding day.
Chief Apihai Te Kawau allocated land to the Crown to establish the city 183 years ago.
The iwi is holding public commemorations around the city this Sunday morning.
Auckland's current anniversary date in January marks the day Governor Hobson dropped anchor in Kororareka-Russell.
Ngāti Whātua Ōrākei Trust chair Marama Royal told Māni Dunlop she thinks Aucklanders will be open to changing the day to a more fitting date for the city.
