It wasn't the cool Auckland weather that gave Usain Bolt the chills today, rather a haka performed by staff at the Frucor beverages factory in south Auckland.
The world's fastest man was in town for a whistlestop tour to promote a sports drink and dropped in to the factory for the haka and powhiri.
Bolt was clearly fascinated by the performance, although he didn't want to get too close to the swinging taiaha.
"It was different, it was good,'' he said. "It gave me the chills, the energy they had. I would love to do something like that. I would love to learn.''
He later turned down the chance at the official press conference, believing ``I would look silly doing it'' without proper instruction, and instead stepped into more familiar territory in a coaching session with eight promising New Zealand track athletes at North Shore's Millennium Institute.
