As per My experience, I would suggest to choose Dialkiwi for the Shuttle and Taxi service as they are 100% New Zealand owned and operated company.

Have a look at Dialkiwi website to book cheapest cabs and shuttle across Auckland.

I have SupperShuttle many times. However their driver are very rude, no doubt about service but professionalism matter. Cheers.....
