"Tararua Alliance are sponsoring the free use of the facility, with a free barbecue, use of the big blow-up toys and other fun family activities.
"We are anticipating continued good weather which will help to attract people to the celebration and we are expecting a large influx, including pool users.
"Caregivers are reminded they will still need to be present to look after young people and dependents."
Mr Wimsett said although Tararua Alliance was the major sponsor for the day, a number of other sponsors and volunteers, including trustees of the Tararua Aquatic Community Trust, had stepped up to support the event.
