"We've done 24-hour turnarounds before, they always have their unique challenges and this will be no different. Not impossible, just challenging."
Auckland hosted Waikato in their semifinal last Saturday at the venue, which has tasked the stadium's ground crew to bring the field up to international cricketing standards for Friday night, as well as a blueprint of how they will tackle the transition back to rugby.
Christiansen says while there is "a bit to do", going from cricket to rugby in such a short timeframe is more desirable than the other way around.
"Doing the cricket first gives you a lot more assurance around the quality of what you're going to produce, and then we go and flip to rugby a lot easier.
"[Rugby] posts will go straight up, you sort of need that alignment tool for putting the field back in accurately, so the first thing is they go up. We've got logos to wash off, so some cricket logos we'll get rid of – that'll be done overnight. When we come in Saturday morning, the field will be ready to have the cricket tray come out and the field marking for rugby just goes straight in. It'll be about three or four hours post-cricket to get it to that stage, and there's the rest of the day on Saturday to sharpen it up. Some people may not even know the cricket was there."
Christiansen says they washed the field straight after the semifinal, making the implementation of the cricket markings relatively easy. What will be difficult is going back to rugby.
"We'll put that field back in on game day… therefore that's another task on Saturday morning.
"That's something that we don't normally do, but it's a lot easier if I do it in the light of day rather than 11pm on Friday night."
The length of grass is also an important factor, particularly given the time of year and the uncommon overlap of the two sports.
"Mid-winter for rugby we're at 34 millimetres cutting height here, and we sort of keep that through until August. Then we traditionally start to bring it down – we might be at 25, and last week we brought it down further," Christiansen says.
"We'll go to 13 or 12 for the cricket."
When asked how that impacts rugby, Christiansen says it will make for a "hard and fast" game.
"We're not going to be able to bring it up too quickly in 24 hours," he adds.
It creates a busy 24 hours where working efficiently is vital for Christiansen and his crew, but he says they wouldn't want it any other way.
"They're all well-versed on it and motivated for it as well. And we've had time throughout the year to think about content that we wanted and now we've got the content, so everyone's pretty happy to have it and there's no complaints from anyone."
