"I will never forget what my own family went through and it saddens me when the same thing happens to others.
"When I hear about these tragedies it is those left behind or waiting anxiously that I focus on.
"By the looks of it, in some of the recent incidents, life jackets were available but were not used."
Otara swimming pool lifeguard Teapanga Varu also spoke about boat safety at the Mangere classes. He has never got over the death of a close friend and his cousin who both drowned at Auckland's Muriwai Beach in 2008 while fishing.
"My best friend was only 20 when he was caught in a rip tide after he went to clean his hands in the water," he said. "He was wearing cut off jeans and the weight of them is what is believed to have contributed to his drowning. His cousin tried to save him but he too got into trouble and died.
"After that I took a big interest in water and boat safety and started passing it on to my community. It is tragic that so many people in New Zealand are still dying of ignorance."
