At terminals that use common check-in for multiple flights, Jetstar has a Queue & Closing Flights person pulling all relevant passengers out of the main queue and sending them aside to a different queue (or double queuing directly at the check-in desk). By T-30, all passengers who arrived before the cut off (for the now closed flight) will no longer be in the original queue. I have witnessed this multiple times for International & Domestic Australia, I assume Domestic NZ would be the same.
