Mike Edwards' career in boxing began as a novice amateur in the 1960s, training under the tutelage of George Cammick at his gym in Otahuhu. Later, Mike would become a successful trainer, working with Anthony Bigeni, the only New Zealand boxer to challenge twice for a world title, and the Australian former pro boxer Paul Murdoch.

Following in his father's footsteps, Mike became a boxing promoter in the 1980s, with his inaugural match, Lance Revill against Monty Betham Snr. Mike's associations include some of the biggest names in trans-Tasman boxing, including Betham, Bigeni, Kipa, Masoe, Murdoch, Malcolm, Tetoros, Pakau, Zohs, Tafua, Revill, Barry and Parker.

Even at 77, Mike still trains most days on the boxing bag and in the ring, either in his garage or at his son David's gym in Pakuranga, East Auckland.
