"It does extremely important work," he said.
The first Fight Night was held in 2012.

NZ Young Farmers members spend months preparing for the high-intensity fights.
"Most participants train in a proper boxing gym two to three times a week from January until the big night," said Courtney.
Olivia Jordan was named the most scientific boxer. Lisa Kendall and Lucy Moss won the award for most entertaining fight.
Spectators sporting giant elbow-high boxing gloves also went up against each other in minute-long bouts.
"It's a bit of fun watching people trying to pummel each other while wearing giant, goofy gloves," he said.
Planning is already underway for the next Fight Night in 2020.
"We're looking for a bigger venue. We want to be able to cater for up to 600 people."
