"The programme also builds their competence and confidence in an around the water."
Mr Gritt said the most important skill for parents was keeping children within sight, sound and reach - without distraction. They had to be able to assess risk and prevent anyone getting into difficulty.
Whanau Nui began as a small programme in the former Manukau City in 2006 and has enrolled 4239 children and 2093 adults.
WaterSafe Auckland will get $970,000 this year from Auckland Council for a range of education programmes to reach 350,000 people.
Plunket also had a message to parents with small children around water - stay close and actively supervise your children, keeping them within reach at all times when they are in and around water.
The agency had teamed up with Huggies on a scheme to give parents a new incentive to enrol their toddlers in swimming lessons, get into the water, hold them close and keep them safe.
Huggies' Little Swimmers will run at selected swim schools throughout the country and all children under 18 months enrolled for term one will get free swimpants.
"[It] will make the transition to swimming lessons so much easier," said Plunket safety adviser Sue Campbell.
Mum keen to ensure lessons hit home
Julie Brien has twice had to overcome her panic and swim out of the clutches of a dangerous surf rip and now wants her children to be able to do the same, if they need to.
"You are having fun in the surf and all it takes is a couple of waves and you're swimming for your life," said the resident of Patumahoe, South Auckland.
Last January, she enrolled with her 9-year-old son Reed (pictured above right) and 6-year-old daughter Indie (left) in the Whanau Nui programme.
"I liked the request that the parents get in pool as well, so even though the course tutors are teaching the child to swim, they are also teaching the parents how to continue the teaching.
"I think our role as parents is to be first educators for children and this is one case we need to take that role seriously.
"I've seen kids terrified to get in the water and parents embarrassed because they don't have the skills to get them in.
"But the tutors have the skills and, within a week, this reluctance will change."
