(1) Subject to this Constitution, an appeal shall lie to the Court of Appeal of New Zealand from a final judgment of the High Court—
(a) As of right, if the High Court certifies that the case involves a substantial question of law as to the interpretation or effect of any provision of this Constitution:
(b) As of right, from any conviction by the High Court in the exercise of its criminal jurisdiction whereby the appellant has been sentenced to imprisonment for a term exceeding 6 months or to a fine of not less than $200, and from any such sentence (not being a sentence fixed by law):
(c) As of right, when the matter in dispute on the appeal amounts to or is of the value of $400 or upwards:
(d) With the leave of the High Court in any other case, if in the opinion of that Court the question involved in the appeal is one which by reason of its general or public importance, or of the magnitude of the interests affected, or for any other reason, ought to be submitted to the Court of Appeal of New Zealand for decision.
(2) Notwithstanding anything in subclause (1) of this Article, the Court of Appeal of New Zealand may, in any case in which it thinks fit and at any time, grant special leave to appeal to that Court from any final judgment of the High Court, subject to such conditions as to security for costs and otherwise as the Court of Appeal thinks fit.
