The Police National Dive Squad is reminding all divers and swimmers to take care of themselves and their loved ones in the water these holidays.

Senior Sergeant Bruce Adams says 73 preventable drowning deaths have occurred in New Zealand waters this year, so he's asking everyone to take responsibility for theirs and their loved one's safety this summer.

'Whether it's young children, your dive buddy, or just a friend you've gone into the waves with, they should always be within reach and in view at all times.

'We have already seen too many tragedies this year involving water activities. This time last year, the preventable toll was 78. We don't see 73 this year as a success - we can do better.”

On average, 83 per cent of these preventable drowning deaths are males.

Bruce is also concerned about inexperienced divers heading out to hunt for Christmas dinner over the next couple of days.

'The Dive Squad have had six diving fatalities to investigate this year and the same issues are often factors that have led to deaths. If you haven't been diving since last Christmas, now is not the time to go straight in for a deep dive.”

The Police National Dive Squad is also reminding everyone to use a recognised dive training provider and not to cut corners by getting ‘trained' by friends or family.

The well-established and recognised schools have the latest information and teach all components required, adds Bruce.

'This might take more time but they provide you with skills for life to ensure you get home at the end of the day.”

POLICE'S SEVEN TIPS FOR SAFE SUMMER DIVING:

1. Always dive with a buddy and stay together at all times.
2. Abandon your dive when issues arise don't wait for them to develop into a very difficult situation to get out of.
3. Abandon weights in an emergency.
4. Get equipment serviced before heading out this summer.
5. Get yourself a check-up with your GP discussing your sport, any medical issues and medications, and assume they are a contradiction to diving until proved otherwise.
6. If you have been out for the water for some time, build up to the deeper dives and get refresher training.
7. Do not push conditions - if it is not calm and enjoyable, save it for another day.
