The last Rotovegas Corporate Fight Night, which was held in 2011, made $25,000 for the club.
Mr Warren spent this on a bus for student transport.
He hopes to raise close to $20,000 this time. Rotovegas Boxing Gym, owned by Mr Warren and his wife Tanya, operates out of a converted garage at their Owhata home.
They have plans for a larger and more central gym which will give some of the city's youth an opportunity to further their careers.
Mr Warren, who won three New Zealand amateur titles in a row in the late 1980s, has been working with kids for about 10 years. "It's not just about boxing; it's about not giving up and self belief. A lot of kids lack self belief, " he said.
"Discipline, determination and dedication are the three Ds, and if you do all three, you will be champion," he said.
Last year 20 of his students competed at the Golden Gloves, a youth boxing competition in Australia, taking home five golds and eight silvers.
Some of the students fundraised to afford the trip, but Mr Warren met the deficit.
To book a table at the fight night call Tanya Warren on (07) 345 3085.
