Midfielder Jack Goodhue has extended his deal with New Zealand Rugby through until the end of next season.
The Crusaders have confirmed Goodhue will remain with the franchise, after penning a fresh one-year deal through to the end of 2020.
The 23-year-old Northlander has won two Super Rugby titles since joining the Christchurch-based franchise in 2017.
He debuted for the All Blacks last year and has since earned seven test caps, establishing himself as one a key piece of their midfield puzzle, as the hair apparent for the departing Ryan Crotty, who heads to Japan after the World Cup.
Flanker Billy Harmon and lock Mitchell Dunshea have also re-committed on the same terms.
Harmon has only played a handful of game for the Crusaders this year, but will likely take on a bigger role next season, as the successor to Matt Todd's number-seven jersey.
Meanwhile, 23-year-old Dunshea has already been thrust on to the big stage in the regular absences of starting locks Sam Whitelock and Quinten Strange.
With Whitelock set to miss next year's competition, he'll be the probable candidate to step into the All Blacks shoes.
The trio join a growing list of Crusaders who have signalled they'll be back for 2020, including Richie Mo'unga, Joe Moody, Codie Taylor, Scott Barrett, George Bridge and David Havili.
