If you travel from the city on a zone 1 service and want to transfer onto a zone 2 or on to the Diamond Harbour Ferry service, ask the driver of your first bus to charge the zone 2 fare or the special fare that applies for the ferry. That way, you don’t pay the zone 1 fare of the first bus and then also the zone 2 fare.
For example: Sally lives in Rangiora and studies at Canterbury University. She travels on the Orbiter to Northlands, then hops on the Blue Line to get home. She tells the driver of the Orbiter to charge her a ‘zone 2’ fare. In doing so, she does not get charged the extra $2.55 for using the Orbiter within zone 1 but only the Blue Line fare of $3.75.
