Neighbours had reported a party at the house overnight, but it had finished by the time the fire broke out.
Ridge, his parents, and his four brothers and two sisters had moved to Victoria about a year ago, where the young man quickly made friends, Mr Hilton said.
"He was pretty popular.''
He was also a talented musician and had written some songs, including a rap song, "Shepparton Rapp (LSC Anthem)'', which his friends played as his body was removed from the property.
Ridge was also known for his skills as a sportsman, playing rugby league for the Pakuranga Jaguars as well as softball.
His body will be brought back to New Zealand, first to his mother's family home in Blenheim before his tangi in Northland.
