( CNN ) -- A New Zealand rugby star has apologized for his reported alcohol-fueled incident last week , when the 2011 World Cup winner is said to have entered a Cook Islands bar naked and wet before assaulting two patrons . According to the New Zealand Herald newspaper , Zac Guildford -- who has a history of drinking problems -- embarked on the rampage on the island of Rarotonga . `` Firstly , I would like to apologize for my behavior here in Rarotonga on Thursday night , '' the 22-year-old said in a statement on the All Blacks ' official website . `` I have no clear recollection of the events of that night but there is no doubt that my behavior was unacceptable and I am hugely embarrassed by what happened . `` I want to apologize to the people who I was involved with and offended that night , the patrons and staff who witnessed my behavior , and the Cook Island people . I am truly sorry for what I did . '' It is not the first time Guildford has found himself in hot water as a result of his off-field antics . He was reprimanded by team management for a similar binge following the All Blacks ' Tri-Nations defeat to Australia in August . The New Zealand Rugby Union ( NZRU ) revealed that the winger -- who scored four tries against Canada in his only game of the recent World Cup -- has been called in front of the disciplinary board on three occasions in the last 18 months . Guildford , who plays for Christchurch-based franchise Crusaders in the Super Rugby competition , expressed his regret for the embarrassment he had caused his family . `` I do n't want any sympathy for the situation I have ended up in , but I am thankful for the support I have received so far from so many people , '' he said . `` It 's obvious that I need help and I want to get home and to get that help as soon as I can . I need to sort myself out . '' NZRU general manager Neil Sorensen defended Guildford , saying he was a good person who is struggling to come to terms with the loss of his father in 2009 . Rob Guildford died from a suspected heart attack after seeing his son score two tries for New Zealand in the final of the Under-20 World Cup in Japan . `` The first thing we 'll do is find out the facts , '' Sorensen told the Dominion Post newspaper . `` The second thing we will do is help the guy if he is in trouble . `` He lost his dad a couple of years ago . He 's also had some alcohol-related issues in the past . He 's a good young man . '' Crusaders coach Todd Blackadder echoed Sorensen 's sentiments , claiming Guildford would benefit from the backing of his friends and family . `` One thing that I do think he needs is to have rugby back in his life , '' Blackadder said . `` He needs the support of all his family and his friends , and he needs to be in a good supportive environment . `` There 's no point in taking him through the judiciary process right here and now when he needs more than that . This is more of an issue than a one-night drinking binge . '' Guildford made his All Blacks debut against Wales at the Millennium Stadium in November 2009 and has represented New Zealand on eight occasions .
