Extradition Treaty with New Zealand, 1970:
“ ARTICLE VII
When the offense for which the extradition is requested is punishable by death under the laws of the requesting Party and the laws of the requested Party do not permit such punishment for that offense, extradition may be refused unless the requesting Party provides such assurances as the requested Party considers sufficient that the death penalty shall not be imposed, or, if imposed, shall not be executed.”
