MC Dennis O'Reilly introduced the members of iwi, hapu, and those helped by Mr Tamati to talk of how he had shaped their lives.
Napier City councillor Maxine Boag said: "Our loss is [Australia's] gain."
To Mr Tamati she said: "What you've done through rugby league has made such a difference in some challenged communities."
To recognise his status as a kahukura, a valued leader in the community, Mr Tamati was presented with a pake kahukura (red-dyed flax cloak) by Taape Tareha-O'Reilly.
The man of the hour was visibly moved by the ceremony.
He said: "It's been a wonderful journey getting involved with the community, and working with the community - that's been the reward for me."
Mr Tamati said he had tried to help youth to realise they had the drive and potential to achieve their dreams.
Some of these were boys from Hastings Intermediate School rugby league team who performed a haka for Mr Tamati, and later created a line to give Mr Tamati a hongi.
