"The tournament came about at Una Purves' funeral in 2010 when a few of us came up with the idea of a bowls match involving just us.
"Una was a very good lawn bowler in her day and loved the sport. She played at the Nelson St club and represented Wanganui in women's competition. So far we have held three annual tournaments in Auckland, Wellington and Te Awamutu.
He said there were several top bowlers in the extended family including Marilyn McLeod from Tauranga - a former national women's singles champion.
"The memorial cup is a coveted trophy to win in our family, but so is the wooden spoon.
"We have both competent bowlers and non-bowlers and we have a get-together usually on the Friday night to choose the skips and draw up the teams, then from the Saturday it's all on."
Gunn said choosing the Wanganui Bowling C club as hosts next year was a no-brainer.
"Not only am I vice-president, but the all-weather greens ensure the tournament goes ahead and it's central with plenty of motels close by," he said.
