Born at Kaiwhaiki marae on the Whanganui River, Simon was of Te Āti Haunui-a-Pāpārangi, Ngāti Apa and Ngāti Tūwharetoa descent. Simon succeeded his father as choirmaster at Kaiwhaiki, recording the series of albums The Valley of Voices, volume 2 of which was a finalist for best Polynesian album at the 1983 New Zealand Music Awards. He composed hundreds of songs, including classics such as Te aroha (1983), and Moe, moe mai rā adapted from the Welsh lullaby Suo Gân, and others for special occasions including one in memory of Sir Archie Taiaroa.
He was the leader of the kapa haka groups Te Matapihi and Te Taikura o te Awa Tupua.
An expert in the Māori language, Simon was appointed an adjunct professor by Te Wānanga o Aotearoa in 2004. He wrote a series of books Taku Whare East about the marae in the Whanganui region, with the third and final book focusing on his home marae of Kaiwhaiki.
In 2012 Simon was awarded an honorary Bachelor of Arts in Māori Performing Arts by Te Whare Wānanga o Awanuiārangi, in recognition of his contribution to kapa haka and cultural stewardship. Simon died in Wellington in 2014.
Māori Party co-leader Tariana Turia paid tribute to Simon, saying "his waiata could move from tempestuous rapids to smooth waters that caress your every trouble away.".
