With many weekday patrols wrapping up around the country, Surf Life Saving New Zealand is urging beach-goers to take responsibility for their own safety in the water.
Riversdale Beach Surf Life Saving Club chairman Dave Rose said now schools are back, lifeguards will be patrolling only on weekends and public holidays.
"It's died down a little bit now but it'll be a busy week with Waitangi weekend, so we're expecting quite a few people and we'll be patrolling over the whole weekend, including Monday.
"After that we're just expecting it to drop down to the usual numbers in February and March.
"If it's a nice day during the week, people will decide to come out and we always welcome them to come to the beach. We just advise people to be safe."
