The proceeds of the fundraising event will go towards getting Trimble and Oakley to Poland.
The evening kicks off at 5.30pm at the Whangarei Squash Club on Tarewa Rd.
Tickets are $30 per adult, $10 children and includes a barbecue dinner, exhibition matches, and an auction.
Trimble and Oakley are also running a one-day tournament during the day of the fundraising event.
This is open to adults and children of any ability.
Trimble and Oakley will be playing in the tournament with one of Canada's top junior players, and spot prizes on the day include a coaching session with one of the players.
