Bay of Plenty Police have issued a warning to beachgoers after two people lost their lives after drowning at Waikawa Beach and Bethells Beach at the weekend.

'It's not surprising, with the wonderful summer weather, that there has been an increase in activity around the water,” says a statement on the BOP Police Facebook page.

Two people drowned on New Zealand beaches over the weekend.

'Unfortunately, it has also brought tragedy with two more people drowning in New Zealand this weekend.

'In the Bay of Plenty wharves are particularly popular swimming spots during the summer, but it's important to remember that the main purpose for these areas is for boats to enter and leave the water.

'So whilst swimming is permitted at certain wharves, there are by-laws in place for the protection of everyone.”

Police ask everyone to encourage friends and family to put their safety first.

They add; 'Whatever the water activity, and wherever the location, it is important that everyone takes the time to find out what rules and advice are in place to help keep them safe.”
