The Crusaders have re-signed a number of players who were set to come off contract at the end of this season, including All Black Ryan Crotty.
Crotty, a versatile midfielder, has signed until the end of 2017, which follows the retention of All Black prop Wyatt Crockett that was announced earlier this week.
Crusaders coach Todd Blackadder said both players would play an important role in next year's side as two of the senior members of the squad.
Joining Crockett and the already-contracted Owen Franks at prop again next season will be Tim Perry. Perry has had a frustrating season on the sidelines after sustaining an injury in the 2014 ITM Cup semifinal, however Blackadder said he would be ready to make an impact in 2016.
Codie Taylor, who has impressed at hooker this year, will also return in 2016, as will young lock Scott Barrett who was catapulted into the starting line-up at just 21 where he held his own alongside All Black locks Sam Whitelock and Luke Romano this season.
Experienced halfback Andy Ellis and youngster Mitchell Drummond will continue to compete for the No 9 jersey next year.
