Not to whom you're directing your question, but I drive the short distance to the car park at the interchange/station, then catch the bus the long distance to the city.
It's a great setup, and/but the very specific infrastructure[0] that I use only services maybe a quarter of the city's mid-suburbia. There's other public transport that services plenty of the rest though.
Auckland is an incredibly busy city, on the same kind of world scale as Sydney, as far as my understanding goes.
The interchange has a four level car park that fills up to about three quarters full by 8am-ish. A secondary car park was just finished maybe a couple of years ago, with an additional ~50% capacity.
