Nzd$5.80peak/$5.22off peak on the AT Hop, vs $16 for Skydrive, for which you have to make a booking, and that booking needs a estimated time of pickup, or $55 (return), or $30 one way, I think, for Supershuttle.
If coming into AKL airport in the morning, after peak, and you have nothing for that first day, and have an AT Hop card, the Air bus from the airport and then train to Britomart is the cheapest.
I will try the Ritchies Skydrive going to AKL airport though, would be like the former Skybus, but they do use the Watervale tunnel, which is faster than Onehunga/Otahuhu bridge way.
Thu 13 Jul, I will be using up the bal of my AT Hop card, they are getting rid of all the individual fare cards over NZ, and use credit/debit cards, but this will have a lot of int fees if your card is not an NZ (bank) issued.
Unless you have a no forex trans fee Aust visa/mastercard credit card.

Just made my first Ritchies/Skydrive booking, quite an easy process.
Hope that the path way from AKL dom to AKL int terminal is now open and walkable, or that the bus driver will drop me off at the int terminal, made a "blue", picked AKL dom instead of AKL int terminal.
Oops.
