The head of the executive branch in New Zealand is?prime min

prime minister吧 我觉得
因为government-general只represent Queen Elizabeth,而且她也只行使皇室的特权权力而已,虽然她在cabinet中担任要职,但the Governor-General's role is almost always limited to ceremonial and non-partisan functions,而prime minister才是cabinet的真正leader,他才是真正行使行政权力的人
