"As a family we had counselling and dad was given the opportunity to create a biography of his life - unfortunately he didn't get to finish it.
"This organisation is absolutely amazing and we want to do all that we can to ensure this support continues for other families in their time of need."
The quiz night will have silent and live auctions and raffles. Two tickets for Ed Sheeran's sold-out Auckland show are among the auction items.
The Wellington family is now calling on local businesses to donate prizes, vouchers or money to go towards quiz night prizes.
They are hoping to raise $5000 for Hospice Waikato.
"We would love it if your business could donate to this worthy cause."
The quiz night is on Friday, August 25 at the Te Awamutu Sports Rooms. Doors open at 6.30pm.
If anyone wishes to donate or reserve a table contact Susan Wellington on 027 361 8320 or wellingtonfundraiser@hotmail.com
