Notable from 2018 is the high number of fatalities in the 65+ group with 18, five more than the five-year average.
"Eleven of these were immersion incidents, where someone has ended up in the water when they had no intention of doing so. Six were swimming incidents so make sure you have support with you or swim in patrolled areas," says Mills.
Immersion incidents are the deadliest non-recreational activity with 28 deaths followed by swimming with 22 deaths.
"Ten of the immersion incidents occurred at home either in home pools, baths or ponds which is a reminder to be vigilant about water safety in the home," says Mills.
Beaches had the most preventable fatalities with 18 followed by rivers with 13. Eight fatalities at beaches involved swimming, while six were land-based fishing.
"Always swim between the flags and whatever the activity follow the water safety code: Be prepared, watch out for yourself and others, be aware of the dangers and know your limits," says Mills.
A big positive is the major drop in powered boating drowning deaths — an 83 per cent decrease on 2017. 2018's total of five boating fatalities (powered and nonpowered) is significant when compared with the 19 in 2017 and the historical average of around 18 each year.
Mills says credit must be given to Maritime NZ, Coastguard NZ and the organisations involved in the Safer Boating forum.
"A decade of work encouraging boaties to wear their lifejackets is paying off. It remains the most important thing a boatie can do to stay safe. In 60 per cent of all boating deaths in 2018 a lifejacket wasn't worn."
The 2018 15-24 age group toll was the lowest since records began half the 2017 total and almost half the five year average.
"Our major safety marketing campaign The Swim Reaper supported by ACC targets this age group so it is pleasing to see the numbers heading in the right direction.
"We are currently doing research around what direct influence the campaign is having on behaviour change," says Mills.
The under-fives toll was three — the same as 2015 and 2016 and a 57 per cent decrease on the 2017 toll of seven.
"Sadly we've had three under-five fatalities already so far in 2019.
"We will continue to reinforce the message around constant active adult supervision of young children at all times," says Mills.
