Auckland Transport chose the path of least resistance for its first big test of Hop cards on trains yesterday - by leaving most new electronic gates open to avoid any passenger crush.
Barriers were kept across only three of 15 electronic gates at peak travel times at Britomart's main entrance to train platforms, as most passengers were ushered off platforms clutching paper tickets.
They were mainly sent in a relatively free flow through alternative manually operated gates while an estimated 15 per cent with new rail-enabled Hop cards were shown how to tag off through ticket readers on the open electronic gates.
At the only other gated station on Auckland's rail network, Newmarket, it was deemed quiet enough for all barriers to operate.
One young man was escorted to the ticket office to pay a fare after an alarm told Veolia staff he had tried to escape charge by tailgating another passenger through the gate.
