"We quite like her there," says head coach Glenn Moore. "She adds a different dimension for us to that position. We have other 12s in the squad who are different (such as Chelsea Alley). But Kelly's got great game vision, has good options when you have to kick, and is a courageous defender."
Moore says the reintegration of the Black Ferns Sevens players has been seamless. They were already very much a part of the 2017 programme from the start, though Fitzpatrick did travel to Canada two weeks ago for the penultimate leg of the Women's Sevens World Series.
The Black Ferns, having survived off a diet of club rugby, a trial, and a heap of training, are champing at the bit to run out in an official international. Moore wants to see a win, no injuries, and some gelling of the structures and strike moves.
"We've done a lot of stuff piecemeal. This week we've tried to bolt everything together, a lot of our plays, set-pieces, strikes, and just doing things well," he says.
Canada should be a stern test, the No 3 ranked side in the world, who pushed the Black Ferns 20-10 in Dublin last November.
"They've had a couple of tests a few months ago. They've typically got a big, strong forward pack, set-piece really well and have athletes with good pace. I guess they are not ranked No 3 in the world for nothing."
The plan is to use all 28 squad members in the three tests, which includes Australia in Christchurch next Tuesday and England in Rotorua, a keenly awaited clash which doubles as the curtainraiser to the Maori All Blacks v Lions game.
"We're playing these fixtures like it's a WRWC-type structure. It's a good chance to change combinations around and about how we recover in short windows. It's all working towards the plan," Moore says.
He is confident that the squad will swiftly get up to speed with the test match intensity, despite no extensive match fitness for most of them other than club rugby.
"We're confident in the programmes we have in place. We've had people allocated in the regions to run our strength and conditioning programmes. We've had a close handle on everything recorded, albeit there is nothing like playing games. The biggest challenge is jumping from club rugby to internationals, but we'd like to think we've done our work."
