The Tiri Cat is a ferry owned by 360 Discovery and used mostly on the Tiritiri Matangi ferry service. Tiri Cat is also regularly used on the commuter Devonport service, when the Kea is out of action. Tiri Cat was previously owned by Fullers and used on the Rangitoto and North Shore ferry services. She was replaced by the Wanderer in 2007.
On May 31 2000, in heavy fog, Quickcat II and Quickcat collided near Bean Rock, causing superficial damage to both vessels. The Maritime Safety Authority concluded both vessels were travelling too fast for the conditions and poor communication took place and the rules of navigation were not followed.
