Infratil supports a national standard for integrated ticketing, but notes the standard will come in after it and councils have invested millions in building systems.

The Wellington-based owner of the Snapper ticketing and payment card system said in its latest investor update that the New Zealand Transport Agency was developing a national standard for integrated ticketing.

Infratil is confident that Snapper is flexible and open and considers that the system was provided without tax or ratepayer support.
