Shaq, 24, has been in the side since 2011 and said he was looking forward to playing at home.
"This time will be different because it's here in Rotorua, it'll be more special. We've never played here before."
Maurice expected the stands to be overflowing with family members.
"It will be pretty packed I'd say. Our entire family, which is quite a large family, will probably be in attendance, as well as the wider touch community.

"We were brought up with touch, our whole family plays. Mum and dad both represented New Zealand as well. We pretty much got dragged to all the trainings and stuff. We were immersed in it so it was pretty much second nature to just grab a ball and start chucking it around.
"We've been lucky to be able to get that connection and play [for New Zealand] together, which will be exciting for this one coming up. Obviously playing with the brother and playing at home is pretty cool."
New Zealand's men's, women's and mixed teams will each play three games against their Australian counterparts. Shaq said any game or series against Australia was hotly contested.
"In the last couple of years it has probably gone up a notch - both nations have put a lot of work in to try to get ahead of one another. I think this series is going to be pretty tough, both teams have a good mixture of experience and newbies.
"Australia have been the world champs since day dot, but we've closed the gap on them in the last couple of years and hopefully we can get one back from them this year."
Maurice said holding the series in Rotorua was "huge".
"Not only for the sport, bringing it out of Auckland, but for the Bay of Plenty and Rotorua community. It's going to be a huge event and it will be pretty special to host it here. It hasn't been held anywhere but Auckland for a long time."
Another Rotorua player to keep an eye on during the series is Mystery McLean, who has been selected in the mixed team.
