Former Blues lock Kurtis Haiu has died at the age of 31 after losing his battle with cancer.
The second-rower made 53 appearances for Auckland Super Rugby side Blues before he was diagnosed with a rare form of bone cancer in 2011.
Haiu was unable to return to resume his career and passed away on Wednesday.
Blues chief executive Michael Redman said: "The Blues family are deeply saddened by this news. Several of our players were close to Kurt and have spent time with him over the past weeks and months,
"It is clearly a tragedy for someone so young, and our thoughts are with Kurtis' family."
Blues captain Jerome Kaino stated: "Kurtis fought such a brave battle. I loved playing footy with Kurtis and I will treasure those memories of my Blues brother and pray that he rests in peace."
Haiu's former Blues team-mate Keven Mealamu tweeted: "Rest well my Brother, Much Love and Blessing."
