It was the volunteers McNab thought of when people were saying "flattering things" to him. "We were working with a massive group of people. If those people hadn't given their time and if we hadn't had the support of businesses we wouldn't have been able to do anything."
He credited the challenge with helping him get a job in operational management for a mining services company in Australia.
Canterbury-raised McNab goodheartedly blames his "meddling" family for the award.
"They nominated me without me knowing."
McNab's uncle, Terence McCloy, takes responsibility for the nomination, saying his nephew is a deserving recipient.
The logistics of organising the student volunteers was massive, but McNab is "one of those kids that whatever he turns his hand to he does really well".
McCloy also feels the award honours the thousands of other young people who helped after the quake.
"The world is full of stories about kids doing crap but [the students] were working for nothing to help people."
McNab will fly to Hong Kong courtesy of Cathay Pacific and stay at the Courtyard by Marriott, with $500 spending money from the Herald on Sunday.
