Ian Foster says Sione Lauaki was a "flawed genius" who helped re-shape the Chiefs.
The assistant All Blacks coach, who was coaching the Chiefs when giant loose forward Lauaki was snared from Auckland, described the death of the 35-year-old former test player as "incredibly sad".
Of his former team mates, Liam Messam - who is playing in the Brisbane 10s - would be taking the news particularly hard.
"Liam and Sione were really close friends," Foster told Newstalk ZB's Tony Veitch.
"When we managed to pinch him in the 2004 draft, he brought a bit of flavour to a hard working Chiefs team and got us into the playoffs that year.
