The Northland Regional Council is urging boaties to familiarise themselves with maritime rules before getting on the water.
The message comes during Safer Boating Week which started yesterday and runs until Friday ahead of Labour weekend, when there will be more beachgoers and boaties enjoying themselves.
NRC harbour master Jim Lyle said the regional council was running a number of safety campaigns online and pointed out four topics on water safety he wanted people to take particular heed of.
They include wearing lifejackets, safe speed, a need for dive flags, and lower waves while crossing harbours.
Mr Lyle said since the number of boaties diving without dive flags was a concern last year, NRC would clamp down hard on those caught flouting the law this summer.
The Coastguard, he said, also ran water safety programmes for students throughout the country and he advised parents in Northland to take advantage of such initiatives.
The theme for Safer Boating Week is Prep, Check, Know.
Associate Transport Minister Craig Foss said with the traditional start of recreational boating season on Labour weekend, now was the perfect time to make sure people were prepared before they got into the water.
