Kirill Koninin always wore a helmet when he went out on his bike - but for some reason on December 23 he made the fatal decision to leave it at home.
Hours later he had suffered a catastrophic head injury and on Christmas Eve his family made the heartbreaking decision to turn the 17-year-old's life support off.
Now they are speaking out in a bid to prevent future tragedies and are urging young people to always - always - wear a helmet.
Kirill's cousin Ilya Zharenikov said the teen was riding his BMX at a skate park in Albany in North Auckland when he fell and hit his head.
"He had so many friends," Zharenikov told the Herald.
"He was so fun to be around, he was very kind.
"My oldest son is 9 and there is a big age difference but Kirill would always come and spend time with my son … they had a very strong connection and that was something very special to me.
"It seems like there's a trend with people not wearing them but it is not cool to not wear a helmet - they are very important and we want to encourage kids to wear them always."
Zharenikov said Kirill's parents hoped to speak to Auckland Council about a memorial bench in his name at the park.
They wanted people to remember their son, what they lost and the potential he had.
In New Zealand it is illegal to ride a bike on the road without a helmet.
A police spokeswoman told the Herald helmets were a legal requirement at all times while riding a bicycle, "no matter where you are riding".
Failure to wear a helmet can result in a $55 fine.
Cycling Action Network spokesman Patrick Morgan said the news of Kirill's death was "terrible".
"It's distressing to hear of the crash... it's sad news," he said.
"Our condolences got out to the family, it's the worst news you could expect."
Morgan said generally New Zealand had very good compliance for helmet wearing - about 90 per cent of people wore them since they became a legal requirement 27 years ago.
"Our advice is simple: ride within your limits, make sure your bike is safe to ride and follow the law."
Police did not attend the crash and could not comment.
Wearing an approved safety helmet dramatically reduces the risk of a skull fracture if your head hits an object or the road, which is why the law requires you to wear one.
A helmet also reduces your chance of getting concussion and protects your head from cuts and scrapes.
