The new Supreme Court of New Zealand was officially established at the beginning of 2004, although it did not come into operation until July. The High Court of New Zealand was until 1980 known as the Supreme Court. The Supreme Court has a purely appellate jurisdiction and hears appeals from the Court of Appeal of New Zealand. In some cases, an appeal may be removed directly to the Supreme Court from the High Court. For certain cases, particularly cases which commenced in the District Court, a lower court (typically the High Court or the Court of Appeal) may be the court of final jurisdiction.
When did New Zealand's Supreme Court come into being?
