The various Facebook tributes included one from former teammate Dwayne Russell.
“Tribute to my good friend and old playing mate Ngati Porou East Coast son Willie Collins who ripped it up on the field every time he bled blue. Petone legend who inspired many and we are all going to miss you. Still cant believe it.”
Ngati Porou East Coast Rugby Union also paid homage on its Facebook page.
“Another Wellington Rugby legend gone to soon. A man making a difference in people’s lives.”
A fitness and boxing trainer, Collins, known as Tou, ran his own fitness training programme, known as Limitless Fitness.
“My goal is to coach and train people to not only meet their goals but to exceed them to maintain their healthy lifestyle and be an inspiration to others,” he wrote on his company website.
Collins was also heavily involved with the Petone Rugby Club and boxing as a fighter and coach. He was diving with two friends at Shark Tooth Point on Sunday afternoon. Wife Joni was on the shore. He failed to surface and after his friends searched unsuccessfully for him, emergency services were called.
A family service for Collins is to be held in Naenae tomorrow and his funeral is on Christmas Eve.
