New Zealand Mirror was a National Film Unit 'magazine-film' series aimed at showcasing Aotearoa to the British market. A Whangarei clock collector is a quirky choice to open this edition of Kiwi reflections. His display includes a clock that goes backwards. The ensuing segments are more in keeping with Māoriland and Shaky Isles postcard expectations. The annual Ngāruawāhia waka regatta includes novelty canoe hurdle races. There are also dramatic shots of 6000 foot high “cauliflower clouds” from Ruapehu’s 1945 eruption, and of the crater lake turned to seething lava.
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.
