Andy Robinson's men won all three fixtures in the southern hemisphere in June, seeing off the Lions' next opponents Australia, as well as Fiji and Samoa.
Only two of the uncapped seven were included in the squad for that trip, with Edinburgh back rower and former Scotland age-grade captain McInally and Glasgow centre Dunbar picking up experience but not featuring for their country in Newcastle, Lautoka and Apia.
"It's some four months since Scotland last played an international, so when the squad reconvenes there will be an element of renewing acquaintances and reigniting the spark and spirit that was such a key part of our success on our summer tour," said Robinson.
"We must look to build on the physical commitment of our players against Australia, Fiji and Samoa.
"Some young players have been brought into the squad. They've been playing well for their clubs and I'm pleased that they've got this opportunity.
"You look at the competition to get in the back row: I could have picked another six players there who I believe would perform well for Scotland.
"It's always an exciting time when the Scotland squad comes together ahead of the first Test match of the season.
"New Zealand are formidable opponents. They do the basics exceptionally well and play with a pace and ruthlessness. It's no coincidence that they are the best team in the world."
Scotland will be without the likes of Chris Cusiter, Rory Lamont, Graeme Morrison, Nikki Walker, Alasdair Dickinson, Ed Kalman and Moray Low through injury but flanker Kelly Brown is fit to feature for the first time since injury robbed him of his country's captaincy prior to last season's Six Nations.
