A close friend to the couple who were killed in a crash in Hamilton at the weekend says they were "devoted parents".
Jeremy and Tania Kay died in the early hours of Sunday morning after their Holden Trax collided with an SUV on the Avalon Drive bypass.
A teenage girl, believed to be their son's girlfriend, also died. The three victims were all passengers.
A close friend, who did not want to be named, said the pair were very proud of their two children, Courtney and Mitchell.
"Anyone who knew them knew those kids were their everything."
Jeremy Kay worked in the dairy industry for about 30 years, 10 of which he was self-employed, but left the industry about a year ago, she said.
He found a second family in the band Tenfoot Leap, which he was the drummer in.
"[The band] was definitely a massive part of his life always making sure we attended any gig possible," she said.
She said the couple were very welcoming.
"They had their fair share of struggles but they were always amazing friends to listen to everyone else's struggles."
"It's absolutely devastating and a huge loss," she said.
The police were yet to lay charges.
The drivers of the two cars, including the couple's son, remained in hospital. Police are appealing to anyone who saw a Toyota Prado driving erratically late Saturday night on the Waikato Expressway.
