The Warriors have moved quickly to secure promising centre Konrad Hurrell on a longer-term deal as the club look to keep some of their best talent at Mt Smart Stadium.
Hurrell, 20, has had his contract extended to the end of 2013 and John Palavi, named the club's 2011 NYC Player of the Year, has signed until the end of 2014 and also been upgraded to join the NRL squad fulltime.
The club also announced former Warriors colts and reserve grade halfback Willie Swann has been appointed the Warriors' new development coach to take over from Ricky Henry, who has been signed to coach the Auckland Vulcans in the New South Wales Cup this season.
"By retaining Konrad and John for a longer term and bringing Willie back to the club we have once again signalled the importance we place on the development area,'' recruitment and development manager Dean Bell said. "Konrad and John have impressed everyone at the club and especially our coaching staff with the way they've developed.
"We work as hard as we can to spot and recruit the best young prospects in this country and then allow our development system to mould them into players who will have a good chance of moving into our NYC and ultimately NRL teams if they're good enough. That's where a coach with Willie's credentials is so important to us.''
