New Zealand's All Blacks winger Zac Guildford apologized for stumbling naked and drunk into a bar and allegedly assaulting two people.The incident happened in the small South Pacific nation of the Cook Islands.

He allegedly punched one man who asked if he needed help and then hit another man across the back of the head.

Guildford, who has a history of alcohol-related issues, made an open apology. Firstly, I would like to apologize for my behavior here in Rarotonga on Thursday night, he said in a statement on the All Blacks' official Web  site.

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.

The New Zealand Rugby Union says it's disappointed that it's happened again, but it's too early for suggestions that he'll be sacked from the All Blacks.“The first thing we're going to do is establish the facts, and then we will say how can we help this kid...because he's only a kid,” the NZRU said.

Guildford made his All Blacks debut against Wales at the Millennium Stadium in November 2009 and has represented New Zealand on eight occasions.

During the World Cup, the 22-year-old Guildford had admitted that he had an alcohol problem and said he was taking steps to bring it under control. In August, he was reprimanded by team management for a similar binge following the All Blacks' Tri-Nations defeat to Australia. 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, he stated.
