National life saving manager Allan Mundy said it is important that people "have their senses switched on" and exercise some caution when heading out into the water .
"People need to take care and understand what risks they may be putting themselves into and take practical steps to avoid them," he said.
"That means not swimming or surfing alone, stopping to assess the conditions and potential dangers and not overestimating your ability.
The Surf Life Saving season officially ends at Easter and volunteer lifeguards will continue to patrol around 80 locations nationwide on the weekends.
Key beach safety messages:
Always keep a very close eye on children in or near the water.
Get a friend to swim with you -- never swim or surf alone.
Watch out for that rip -- rips are calm, deep patches of water close to shore that can sometimes have waves breaking to the side. Rippled, discoloured or foamy water with debris can also mean there is a rip present.
Don't overestimate you or your children's ability to cope in the conditions. Even waist deep water can be life threatening if you step in a hole or get hit by a large wave. Preferably be in the water within arm's length of them at all times on a surf beach.
If you're away from home, check with the locals and ask them about the conditions and the safest place to swim. Or go online and find the closet patrolled beach at findabeach.co.nz
If in doubt, stay out!
