The Wesley College product's international career ended in 2003 when he decided to focus on managing his health issues.
Lomu represented three New Zealand provincial unions, Counties-Manukau, Wellington and North Harbour and three Super Rugby franchises, the Blues, Chiefs and Hurricanes. His overseas clubs included Marseille and Cardiff Blues.
A 2011 International Rugby Board Hall of Fame inductee, Lomu will use his visit to Hawke's Bay to promote My Story, an update to his 2004 biography.
Avid rugby fan and staunch supporter of the Tamatea club, Ngati Kahungunu Iwi Incorporated chairman Ngahiwi Tomoana, was thrilled to get the thumbs up from Lomu for the October 18 function to be staged in the Hastings Sports Centre.
"We're delighted Jonah has accepted our invitation. He's the world's first rugby superstar and even though he's been out of rugby for a decade, he's still in hot demand all over the world. We're the first iwi to host Jonah Lomu at our iwi awards and we're excited to give him an awesome Kahungunu experience," Tomoana said.
Guest artists for the night are the "Delicious Dance Crew" a Pacific Island version of Maoridom's J Geeks.
"They will entertain us and have us in fits of laughter," Tomoana added.
In a change from previous awards, category winners have been announced a month out from the function. However the winner of the premier award, the Ngati Kahungunu Iwi Incorporated Maori Sportsperson of the Year, won't be announced until the night.
All category winners become automatic nominees for the premier award.
