When Mount Tarawera erupted on 10 June 1886, it took over 100 lives. It was also thought to have destroyed the Pink and White Terraces on Lake Rotomahana, then hailed as the eighth wonder of the natural world. This documentary follows a team of New Zealand and American scientists — led by Kiwi geologist Cornel de Ronde — as they scour the lake floor, to see if any traces of the legendary structures remain. Also examined are the area's history, and the lead-up to the eruption. In 2018 de Ronde robustly criticised a theory that the remains of the terraces were now partly on land. 

This 1982 Kaleidoscope report interviews artist Theo Schoon, on his return to New Zealand after a decade in Sydney and Bali. Schoon was a pioneer as a Pākehā engaging with Māori design, melding modernist and Māori motifs (e.g. moko and kowhaiwhai patterns). He discusses his earlier estrangement from the New Zealand art world ("talking to the deaf"), his eight years documenting Māori cave drawings ("art galleries of a sort, art galleries that I'd never been conscious of"), growing and carving gourds, and being inspired by Rotorua’s geothermal activity. Schoon died in 1985.
