New Zealand is part of the common law tradition, so judicial decisions are a source of law, and the doctrine of stare decisis applies.
For NZ court decisions made prior to January 1 2004 the Judicial Committe of the Privy Council (London) was the final court of appeal.
Since 2004, NZ has an independent hierarchy - with the NZ Supreme Court the final court of appeal.
But NZ courts continue to consider developments in other common law countries - principally but not exclusively England & Australia - when reaching their own decisions.
