Jimmy Thunder

Peau died in his sleep in Auckland on 13 February 2020, following brain surgery.

Peau married his second wife, Iris Whitemagpie, a Native American in 2008. The two met in 2006 and got married at Whitemagpie's reservation in Arizona in a cultural ceremony. He had three children in New Zealand, from his first marriage. His eldest son, Louis, was selected for the Samoa national rugby league team to play an Australian selection side in 2010. He also represented the Mt Albert Lions at domestic level, playing at second-row.

After retirement in 2003, it was reported Peau was in financial debt. The Sunday Star-Times discovered he had been living homeless on the streets of Las Vegas in Sunset Park. World Boxing Hall of Fame inductee, Thell Torrance reported Peau would ask for handouts and turn up to boxing gyms, offering himself for sparring work and was often turned down due to poor conditioning. It was later revealed by close family he was given casual laboring work in a rehab center run by Native Americans and became a personal trainer and part-time bodyguard.

Thunder turned pro in 1988, after being omitted from New Zealand's Seoul Olympic Games team. He changed his surname from Peau to Thunder in 1989 at the suggestion of his manager at the time, Jack Rennie. Later in his professional career he also fought under the name James Thunder. Among his notable victories are wins over Tony Tubbs, Craig Peterson, Trevor Berbick, and Tim Witherspoon. On the 18 March 1997 edition of the USA Network's Tuesday Night Fights he knocked out Crawford Grimsley with his first punch, scoring one of the fastest knockouts in history at 13 seconds. He finished his 49 fight career with 35 victories, 28 by knockout. Throughout his career he won regional titles including the Australian Heavyweight Champion twice as well as winning the lesser IBO and WBF Heavyweight titles.

He went to school at Onehunga High School in Auckland. His friend introduced Thunder to Gerry Preston. Preston took on the young Samoan into his boxing gym in Mangere Bridge. In his early amateur days, Thunder became the first Samoan-born fighter to win a gold medal in the heavyweight division, representing New Zealand at the 1986 Commonwealth Games in Edinburgh, Scotland. He defeated Dougie Young in his hometown by unanimous decision. It was one of the nine gold medals won for New Zealand in that year. As an amateur he had 89 fights, finishing his amateur career with 83-6 record.
