Regardless, it appears the feedback from players and coach Steve Hansen about the tough nature of the latest tour in November and December has hit its mark and that extra test at the end of the year is looking less likely.
This year the All Blacks demolished Scotland, accounted for Italy, were excellent against Wales until the latter stages and hardly fired a shot against England.
Tew said he was aware of the demands placed on the All Blacks, especially those who have families, and that they are also integral to the success of their Super Rugby teams.
"The thing about the extra game, as an example, is that we're now able to sit back and say 'what's the best rugby outcome from the discussions for an extra game?'," Tew said.
"Would the All Black coaches and players see an extra game as beneficial for 2015 or is getting back and having another week off and getting back into Super Rugby earlier the better option? That's the discussion we're able to have rather than when we set up for 2012 three years ago when we desperately needed to play this extra game, and in fact the third Bledisloe is also a revenue earner. This year we put two extra matches into the schedule which earned us a considerable amount of money.
"The majority of guys who toured went and did another three or four days of commercial work and didn't get back until the weekend," he said.
"So it is a very demanding end of a tough year for our guys and we're keen to manage it. But we also don't want to take a knee-jerk reaction to a performance against England that didn't match up to what we'd expect.
"Now that we've locked in a considerable proportion of our commercial revenue we can make our decisions based on what's best for the team rather than necessarily having to take the money thing into account."
Tew said Hansen would have an input into next year's schedule.
"I've been talking to Steve on a regular basis and it's fair to say he's waxed and waned a little bit. There is an argument that having an additional game better mirrors what 2015 is going to be like."
Tew said he wasn't aware of any other All Blacks starting next year late. Keven Mealamu will relinquish the Blues captaincy to take an extended break, while Richie McCaw is taking a sabbatical and will miss the France tests and first part of the Crusaders season at least.
Tew said other players, such as Hurricanes skipper Conrad Smith, could take a sabbatical in order to stay fresh for the 2015 World Cup in England and Wales.
