The 25-year-old, who has also had spells with Melbourne Storm, Wests Tigers and Manly Sea Eagles during his career but played only one NRL game, is set to arrive in the country tomorrow lunchtime.
With club captain Terry Campese sidelined for the rest of the campaign, Chisholm will provide cover for half-backs Albert Kelly and Maurice Blair as well as adding further competition for places across the back division.
Kelly suffered a knee injury in the 31-18 defeat at Salford Red Devils on Sunday but trained partially today and will be given until the last hour to prove his fitness for Friday’s crucial derby against Hull FC.
Chester says it is unlikely Chisholm will be considered for that game, even if Kelly fails his fitness test, as youngster Matty Marsh is waiting in the wings.
But he said: “We are delighted to be able to bring in Dane at this stage of the season and we’re looking forward to having him on board.
“He’s been really impressive for Canterbury’s reserve grade side this year and he’s an exciting player to watch.
“As well has having plenty of experience at playing in the halves, he’s got blistering pace and he’s a great finisher too, so he gives us plenty of options.
“Canterbury have re-signed Dane for next season, a sign of their high regard for the player, but a move to us for the rest of this year is a deal that suits all parties.
“It will allow Dane to show what he can do in the first team and I know he’s really excited about playing in Super League and for Hull Kingston Rovers.”
Chisholm has scored three tries in four international appearances for France having qualified through his mother and, therefore, does not count on the club’s overseas quota.
Hull KR need to win both their remaining games - against Hull and at St Helens - to quality for the top eight but, if they don’t, the new signing will certainly prove useful for the Middle Eights battles ahead and, of course, their Challenge Cup semi-final against Warrington Wolves.
Rovers chief executive Mike Smith added: “I’d like to thank everybody at Canterbury and head coach Des Hasler in particular for allowing a player who has been an integral part of their reserve team this season to join us on loan for the rest of the year.
“The Canterbury club has been a pleasure to deal with throughout and whilst it has taken a lot of work to get the deal over the line, we were delighted to be in a position to announce Dane’s move on his arrival in the country later this week.”
KR have lost John Boudebza, James Greenwood and Jordan Cox from last week but Tony Puletua - unable to play against parent club Salford - and on-loan Greg Burke are recalled with Marsh also added.
Hull, who sit eighth ahead of ninth-placed Rovers by just two points, could have captain Gareth Ellis and fellow second-row Mark Minichiello back in their side as they seek a third successive win.
