One of the primary objectives of the panel is to examine New Zealand Rugby's treatment of, and attitudes towards, women.
The sporting body has never had a female board member in its 124-year history.
"We've got a lot of high-profile New Zealanders there. They'll meet three or four times between now and the draft report, being due some time around March-April next year. But if they want longer, we'll give it to them," Tew said.
"We're in their hands, we're very grateful they've put their time and reputations on the line to help us. We're looking forward to learning their view of what we're doing and what affects us that comes from society and how we can deal with it.
"I think there'll be some good things for the whole country to listen to."
Tew said the year wasn't all bad, citing good participation numbers, good growth in the women's game and how every season is "challenging".
However, while the action on the field has largely been excellent, it has been overshadowed by a string of off-field embarrassments.
Tew says he wants to look at it as an "opportunity".
"Nothing's sacrosanct and we're going to co-operate fully with that group and hopefully, we're going to learn some lessons."
Asked to go through each of Kiwi rugby's scandals of 2016, Tew said "that would be a very long interview".
"If you come back to the Chiefs thing, clearly the first mistake was our players made a poor decision to hire a stripper.
"We probably underestimated peoples' response to the fact we conducted the investigation - I think very well - but on our own, we didn't bring anyone in independent which would have given it more validity," he said.
"And in the [Losi] Filipo case, I'm not sure what else we could have done, frankly.
"That assault happened when the kid was still at school and Wellington had employed him I think in good faith on a contract because the justice system had dispensed their justice, and he was a free citizen to carry on working in our environment.
"Clearly we underestimated the response that the victims of that particular instance would have and it took us a bit of time to catch up.
"We're sorry we've upset some people in that regard and we'll learn from it."
