To the delight of Warriors coach Andrew McFadden, Konrad Hurrell is in good shape and giving his all at training this week.

Konrad Hurrell admits it's time to grow up.

The Warriors centre has had his worst year as a professional footy player, but says he's determined to learn from his mistakes and repay the club's faith.

"Next year will be very different for myself. I'll try to be professional off the field as well as on it," Hurrell said.

Hurrell's 2015 season was a nightmare. The lowest point came when he put photographs of himself on social media partying at a concert in Auckland two days before the Warriors were thrashed by the Tigers.

He also suffered a form slump and was whacked with a three-week suspension in May for kneeing the Sharks' Anthony Tupou in the face and breaking his jaw.

Relations between Hurrell and Warriors coach Andrew McFadden and others at the club were strained – to the point where they came close to parting ways shortly after the season finished.

The 24-year-old still has three years left to run on his contract, which he wants to see out, but concedes he's let himself down in his preparation for games.

"When I'm at training I've always done my best there, but sometimes off-field I've slept and ate badly, and that all comes back to bite me when it comes to the games," he said.

He's spent the past couple of months reflecting on his behavour and realises he has to change. He wants to put 2015 behind him – and needs to learn from it.

"I've got to take what I did right over the past couple of years, but also look at what I've done wrong and what I can work on," he said.

"I've been doing that with my managers and also the coach, too.

"I'll try to eat good, train and sleep well, it's those little things that I need to go back on and be better at."

Despite his disappointing season, he remains a charismatic figure at the club – but as his impact at the club wanes, so does his popularity.

He only played in half of the team's 24 games this year, scoring just four tries. In 2014 he scored 12 tries in 19 games.

And those off-field indiscretions meant the Warriors had a readymade scapegoat for the team's poor performances. The end result was it loooked like Hurrell didn't care.

Hurrell promises to change his ways.

"I'll be more professional about social media now," he said. "All kids out there have Instagram or Facebook now, and I've got to think about that and be more mature.

"There are times to muck around, but there are other times when you have to put your head down and be serious.

"There are little kids out there who look up to us."

Hurrell started 2015 getting over a wrist injury, which limited his pre-season. He picked up a knee injury in the season opening loss to the Knights and the rest of the campaign was blighted by injuries, suspension and spells playing in the reserves. His season never got out of second gear. Despite the Warriors being ravaged by injuries towards the end of the season and the team in freefall, Hurrell could only make it to the interchange bench for the last three games.

The season was barely over when Hurrell was linked in October to a move to Super Rugby with the Hurricanes and Blues, as well as Wigan and a number of other NRL clubs. At a crisis meeting with Hurrell, his management and the club, it was decided he would stay – if he turns things around.

"The Warriors want someone who wants to train hard and gives everything to the club," Hurrell said.

"They don't want to pay someone who comes in and just mucks around.

"So after all of that happened, I realised what my future is. They've given me their all and now it's my turn to work hard for them.

"Hopefully this is going to be a great year for the Warriors and I'm busting my ass to be a part of it."

And it hasn't been all talk. Hurrell is looking noticeably trimmer – and Warriors recruitment and development manager Tony Iro says everyone has been impressed with him.

"I think this is the best shape he's been in, to be fair," Iro said.

"He came back a little heavy last year, struggled with some injuries and couldn't get to his best. And it caught up with him at the end.

"But he came back in great shape for the first day of training and like the rest of the boys he's working really hard.

"Whenever you present yourself on the training paddock, your physical appearance is usually a good indication of whether you're doing stuff right off the field.

"Now he's looking in good shape, by all accounts he's eating the right things and doing what we expect of our fulltime professionals.

"He's a long way ahead of where he was this time last year."

A fit and focused Hurrell in 2016 would be like a new signing for the club, Iro said.

"He's one of a few guys that we're hoping have learnt a few lessons from the last 12-18 months and are ready to take that next step."
