Overall, 90 people - mostly men and including eight pre-school children - drowned in New Zealand last year.
None of those were at patrolled beaches and at the 80 patrol locations around the country.
Last month, water safety organisations joined together to develop a collaborative plan to address New Zealand's high drowning toll - setting ambitious new targets in the process.
Mr Dalton said it was time the public realised just how serious New Zealand's drowning toll was.
"It's sad because the beach is New Zealand's favourite playground but it can also be extremely dangerous.
"If people can change their 'she'll be right' attitude towards surf safety, so they don't underestimate the risks and overestimate their own abilities, then we will be on our way to helping reduce drowning on our beaches."
Traditionally, the Surf Lifesaving patrol season began at Labour Weekend and continued to Easter.
