The Olivine Ice Plateau is a glacier in the Olivine Wilderness Area and Aspiring National Park in New Zealand's South Island. The Plateau is named after the mineral olivine, which is common within the Dun Mountain Ophiolite that underlies the area. The Plateau extents to the west over the Forgotten River Col. into the Forgotten River and to the North it merges with the Andy Glacier, which feeds a tributary of the Arawhata River. The Olivine Ice Plateau is one of many glaciers in the region of the Arawhata, Dart, Hollyford and Matukituki rivers' headwaters.
