Neil gets his first ever glimpse of a live volcano; Jacky hunts for apostles from Gisborne's Age of Aquarius; and Matt dives into a tale of tragedy, treasure and treachery in Mahia.

Neil uncovers an invasion that ruffled more than a few feathers in the Abel Tasman National Park and learns how to save whales, while Matt goes in search of the Mikhail Lermontov.

Tonight Neil steps onto Tmaki Makaurau's biggest volcanic eruption; meets the Kamikaze surfers who fought to make New Zealand nuclear free; and goes paddling, Piha style.

Neil visits the Royal Albatross as they return home from their wanderings; Riria unveils the mystery of a precious relic; and Jacky revs up the beach at the Burt Munro challenge.

Neil visits a mansion once owned by Terry Clark of 'Mr Asia' drug syndicate fame; Riria takes aim at the musket wars; and Jacky gets jazzy in the world's largest seacave.
