His mother, Bridget, Smith accepted both awards on his behalf.
"From the words of Aaron, we smashed it," she said.
Harris, 23, who captured the Junior Sportsman award at the 2010 edition of the annual function, was a key member of the Kiwis team which beat the Kangaroos 26-12 in the Brisbane-hosted Anzac test. That was the Kiwis first win in the annual fixture since 1998.
Another of his highlights this year was helping his Melbourne Storm team beat the Dragons in the July NRL clash at Napier's McLean Park. The cultural experience Harris and his Waipatu Marae-based whanau gave the Storm team had many of his Aussie teammates, including Kangaroos captain Cameron Smith, awestruck. In his guest-speaker role, Harris told the crowd he had not thought about playing for the Kiwis when he first ventured across the Tasman.
"I didn't realise the opportunities I had were there.
"I'm lucky to be part of such a good time for the team and lucky to be part of such a good team."
During a Q and A stint with the crowd, Harris was asked if he would consider playing for the Warriors. He replied: "I'm quite happy in Melbourne at the moment."
This year, All Black Smith put daylight between himself and his nearest rivals for the test No9 jersey with some superb performances for the Highlanders, who won the Super Rugby competition.
His mother recalled how he used to pass a ball to a wheelie bin to improve his speed and accuracy.
Harris and Smith beat the winners of the eight other awards for the premier award.
They included Manawatu's New Zealand Women's Sevens vice-captain Sarah Goss, who won the Senior Sportswoman award, and Junior White Sox softballer Mereana Makea, who won the Junior Sportswoman award.
Makea is the grand-daughter of a former premier award winner, multiple national title-winning softball coach Tom Makea snr. With Courtney Gettins having won this award in 2014 and 13, Makea completes a White Sox treble.
Top Hawke's Bay touch referee Zane Johnson collected the official award for the third time and second consecutive year. His son and fellow touch ref Zarne Johnson has won it four times.
Nuhaka's Manutai Marae took out the MaraeFit Marae of the Year award.
The inaugural Kahungunu Outstanding Sporting Achievement award was captured by Otane rugby stalwart Kelly Graham in recognition of his 400 consecutive games for his club's senior team.
