For soundchecks, what GG2 said.
For actual rehearsals during the days prior to the start of a leg, they will sometimes do an afternoon session, but prefer evening sessions. Can be a bit pot-luck whether they start closer to 6pm or 9pm. And since this leg is well into the tour and not after an extended downtime, I'm not sure they will do extensive rehearsals in the nights before the first Auckland show. Maybe just the night before?
