Manu Vatuvei is back training with his teammates after being on medical leave.

The six Warriors penalised for breaching team standards have been 'fully reintegrated' into the Warriors' NRL squad, the club says.

Warriors managing director Jim Doyle said Ben Matulino, Bodene Thompson, Konrad Hurrell, Sam Lisone and Albert Vete had trained last week while Manu Vatuvei, who was on medical leave, had rejoined his team-mates.

It's been reported five of them had admitted mixing prescription pills with energy drinks on a night out after the Warriors were thumped by the Melbourne Storm just over two weeks ago. Hurrell said he had not taken the pills.

The full squad is available for the match against Penrith in Christchurch on Saturday.

​Doyle said the six players "penalised for breaching team standards have been fully reintegrated" into the Warriors' NRL squad.

They had already apologised to their families, teammates and the club's football staff, he said.

On Monday they apologised to all Warriors staff, sponsors, members and fans.

"We're sorry for the embarrassment we've caused everyone who works for and supports the club," they said in a statement.

"We didn't meet club standards and know how much we have disappointed our families, teammates, staff, sponsors, members and fans. Most of all, we let ourselves down.

"We have a lot of work to do to regain respect from those around us but we are fully committed to showing them how much they mean to us and how much we care for our club.

"We'd like to thank everyone who has supported us over the last week, especially the people at the club. Now we just want to look ahead and do all we can to help our team and the club."

Doyle said discussions with the players were ongoing.

"We continue to work with them on welfare and education matters," he said.

"We've also readdressed team standards with the entire squad."

Warriors head coach Andrew McFadden said his sole focus was now on football.

"Today is very much about moving forward for us as a club with a huge game this weekend against Penrith in Christchurch," he said.

"While there is much we have learned from the past week, we are committed to ensuring we have a squad fully focused on the primary role of preparing for and playing against the Panthers this week."
