I noticed on the bus a flyer announcing weekly Go Rider passes from 30 August available for $40 a week. I haven't seen it announced on the Maxx website.
If true, this is an excellent deal and a template for a future integrated ticketing fare structure:
$40 a week for all your public transport needs with in the Auckland super city, cheap and easy to understand, buy, validate and use.
No need for zoning, no discrimination between transport modes (valid on buses, trains and ferries, including Waiheke) and times of use.
