Colin Munro who is suffereing from his hamstring injury which kept him out of the third and final T20I against Pakistan is expected to be fit for the clash on February 3.
New Zealand selectors decided to name a 14-man squad for the game, with Lockie Ferguson and Glen Phillips missing out. Munro picked up the injury in the second T20I and was rested as a precautionary measure.
"Colin has been assessed and we're optimistic he will be fine by Sunday," New Zealand selector Gavin Larsen said. "We've seen how big an impact Colin has in white-ball cricket, so we're looking forward to having him back.
The selectors went ahead with a spin-heavy side by bringing in four spin options in the side. "Historically we've seen that the SCG can spin a little bit, so it's important that we have options in that area," Larsen said. "Mitchell and Ish are our key guys, but having the likes of Anaru and Kane to do a job if need be is important as well."
New Zealand will return home to play their remaining matches after the first T20I against Australia. They next take on England on February 13. The final will be played in Auckland on February 21.
Squad: Kane Williamson (capt), Tom Blundell (wk), Trent Boult, Tom Bruce, Colin de Grandhomme, Martin Guptill, Anaru Kitchen, Colin Munro, Seth Rance, Mitchell Santner, Ish Sodhi, Tim Southee, Ross Taylor, Ben Wheeler
