The rise in popularity of freedom camping and Airbnb has given caravan clubs competition forcing the Rivercity Caravan Club to put the call out for members.
The club started in 1975, as a breakaway from the Whanganui Caravan Club, which was overflowing with members.
Current chairman Graeme Rapson joined two years later.
"I got into it through my parents and older brother, who took part in the second ever Rivercity rally," he said.
Rapson said that in those days you could expect up to 30 children to come along on trips all over the North Island.
