The traditional Maori name for the glacier is Te Moeke o Tauwe, which means the bed of Tauwe. After Tauwe's death, Hinehukatere was heartbroken and cried so many tears. These tears froze to form Franz Josef Glacier. The Maori name for Franz Josef Glacier is Ka Roimata o Hinehukatere which means the tears of Hinehukatere. The area was, and continues to be, an important source of pounamu greenstone or jade. This precious stone is used for making Maori tools, weapons, and jewelry. Te Wahipounamu was added to the UNESCO World Heritage List in 1990. The Westland and Mount Cook National Park and the Fiordland National Park were previously inscribed on the list, but are now considered under Te Wahipounamu, which covers all of these areas. To be inscribed on this list, Te Wahipounamu met several criteria. It contains many of the natural features that contribute to New Zealand's reputation as a place with exceptional landscapes. It is considered the best modern example of the biota of Gondwanaland and is therefore of global significance. There is a high degree of geodiversity and biodiversity and the habitats are largely unmodified. And finally, there is an extensive range of New Zealand's unusual flora and fauna, which demonstrate its evolutionary isolation. Most of the land in Te Wahipounamu is owned by the Crown (government and the people of New Zealand) and administered by the Department of Conservation (New Zealand). The most important regulations are the National Parks Act 1980, the Conservation Act 1987, and Reserves Act 1977, which were not made specifically for Te Wahipounamu but apply as they are for all of New Zealand. There is a legislative mandate for the preservation and protection of natural and historic resources to maintain their intrinsic value, provide for their appreciation and recreational enjoyment by the public, and safeguard options of future generations. The Treaty of Waitangi grants the Ngāi Tahu people prestige and authority over the land. The Department of Conservation is obligated to oblige to the principles of this treaty. This implies a partnership agreement with the Ngāi Tahu people. This partnership involves an annual business planning process with the Ngāi Tahu iwi (the overarching tribal authority), which gives the Ngāi Tahu an opportunity to engage in and contribute to the operational management of the property. The treaty was not always honored though, but a settlement was made around the time Te Wahipounamu was declared a World Heritage Area.
