Napier Boys' High School has paid tribute to a former student who died after a naval diving training exercise in Devonport on Monday.
Zachary Yarwood, 23, attended the school from 2010-2013 and was described as a much-loved student by all.
"The staff remember Zachary as a lovely young man who was always cheerful. He had a passion for football and was totally committed to every tackle, a really gutsy young man," a school spokesperson said.
"We extend our deepest sympathies to Zachary's parents, siblings and extended family."
A New Zealand Defence Force spokesman said Yarwood was taking part in advanced diver training in about six to eight metres of water when the incident happened.
