The test against the USA in November and the one two weeks later against Scotland would be obvious games for Barrett to start at first-five, but Daniel Carter has once again muddied the waters.
Carter is expected to have recovered from his broken leg later this month and, having been on sabbatical for the first six months of this year, the plan may well be to run him into form on the European tour as happened last year.
Gazing into the crystal ball, Barrett's opportunities to start are limited, which is why this Saturday's test may be the right game for him to be given the jersey he covets.
The intrigue mounted yesterday when his girlfriend tweeted: "All good things come to those who wait". Could Barrett have been shoulder-tapped by coach Steve Hansen?
The perils of the modern age warn against reading too much into a cryptic message posted through social media. Those inclined to brand that tweet a red herring could point to the fact that Cruden played his best test for the All Blacks at Eden Park and it would make no sense to reward him with a seat on the bench.
And yet perhaps that's why the selectors feel they should inject Barrett this week. There would be no ambiguity: it would be a definite case of Barrett being given an opportunity rather than Cruden being dropped.
It would be unusual for this selection panel to make a non-enforced change but there are different rules when it comes to first-five.
Coming off the bench after having had time to assess the opposition is a specific skill Barrett has acquired - but it's a different business starting.
