New Zealand bathymetry and topography.

A heightmap of New Zealand and it's submerged continental fragment Zealandia. The data is from the NIWA bathymetry map found here https://www.niwa.co.nz/our-science/oceans/bathymetry . I had to reduce the file size considerably which meant that the mountains (above sea level) lost a lot of definition. To combat that I replaced the mountains on the mainland with the other heightmap of New Zealand shown, which is from https://www.reddit.com/r/newzealand/comments/1c170r/grayscale_altitude_map_of_nz
