Restore passenger rail protestors say they will continue their protests despite an altercation yesterday with a driver just north of Wellington's Terrace Tunnel.

The frustrated motorist took the law into his own hands attacking the small group of climate protesters, shortly after 8 o'clock Monday morning.

The Restore Passenger Rail group has been running what they call a civil resistance campaign over the last year, bringing rush-hour traffic to a standstill on several occasions.

The group's spokesperson, Joseph Fullerton, says they're not entirely surprised by Monday's outburst against their protestors.

Fullerton spoke to Charlotte Cook.
