After reviewing the New Zealand judicial authorities on privacy, Gallen J stated: "the present situation in New Zealand ... is that there are three strong statements in the High Court in favour of the existence of such a tort in this country and an acceptance by the Court of Appeal that the concept is at least arguable."
