A Surf Lifesaving manager says Coromandel's Hot Water Beach will need to be patrolled for up to half the year if tourist numbers continue to rise.
The organisation's eastern regional manager says the beach is a popular destination for tourists and holiday-makers who often visit throughout the year.
Chris Emmett says this, and the increasing number of tourists, is putting added pressure on lifeguards.
If it continues, he says Hot Water Beach will need an active lifesaving service for five to six months of the year, including mid-week days when volunteer lifeguards are at work.
Mr Emmett says more funding will be needed for that to happen, and the organisation will be working with councils in the area over next three to five years to help meet the demand.
