Stunning shots of the changes the Kaikoura earthquake did to parts of the South Island show what otherworldly landscapes are lurking just beneath the ocean's waves.
The Reef Uplift Research Consortium, put together by the Marine Ecology Research Group at University of Canterbury, is investigating the changes, including massive swathes of land that used to be underwater now poking above the surface.
While most of the tectonic shifts occurred around Kaikoura on the east of the South Island, change happened as far away as Okiwi Bay, near Nelson.
Markers left on what used to be the seabed show how the lack of algae is contributing to erosion.
Maps of the area may have to be redrawn, so much new land has appeared.
This is most evident in aerial shots of the region, especially around Kaikoura itself.r
The Reef Uplift Research Consortium's findings were presented at a marine conference in Christchurch earlier this week.
