Do I need to do manual checkin flying without checked baggage on Air NZ?

[pacifictraveller01]

Hello, newbie here, not really a FF question but I'm flying with Air New Zealand from BNE-AKL return next month. I plan on just taking carry on luggage for the 2.5 day trip. Do I need to do any manual check in or passport check at the Air NZ counter at Brisbane Intl. Airport? Or can I do it all online and go straight to security? I have an Australian passport. Thank you

Flying earlier this month on the same flights I online checked in through the airnz app (you need to load your passport details). HLO I only had to have my passport verified at the gate (both BNE and AKL).
I think this beats having to line up at the counter.
