Whanganui Maori activist Ken Mair says he's heading into a celebrity boxing match against former mayor of the city, Michael Laws, with plenty of confidence.
Despite a history of bad blood between them, the two have agreed to a fight on Saturday to raise funds for people in Christchurch affected by the quakes.
Mr Mair says he's motivated to win, not only because of the rivalry between the two but also because it's for a good cause.
He says he'll go into the ring hard and will be mentioning some of the comments Mr Laws has made about the spelling of Whanganui and how it's undermined the integrity of the local iwi.
Ken Mair says he's looking forward to putting into action all the training he's had over the past few months.
Micheal Laws says he could be in trouble as a broken bone in his right hand has interfered with his preparation for the fight.
