Guided day trips to Mana Island, a DOC scientific reserve about 20 minutes by boat from Mana Marina in Porirua. The day starts with the boat ride, then a 20-minute talk at the historic woolshed about the island's human and natural history, then a self-guided walk. The team points out tracks and the best spots for flora and fauna. Private and tailored trips for groups of 10 or more can be arranged. The boat, the Mana Island ferry, carries 35 people. The company says it is the only official charter to the island, and it runs day trips only, as DOC does not permit overnight stays. Trips run seasonally from spring to late autumn, and bookings and availability are on the website's calendar. The island has a moderate fitness requirement, because passengers walk up and down a ramp and a few steps when the ferry lands. Mana Island has a takahē population, along with 39 other bird species and several lizards.
