I've had a similar experience with a connection time of ~55 minutes when connecting through YVR to AKL. The short connection wasn't planned but a delay at ORD created a bit of excitement (read: chaos) in advance of my vacation.
As others have said, it should not be a full blown immigration screening so unforseen events aside, I'm assuming you'll be ok. Good luck!
