Less well known are the ways in which settler churches of Aotearoa New Zealand reached out to engage in missionary activity in other parts of the world. Pushing Boundaries is the first book-length attempt to tell the story of the evolution of overseas missionary activity by New Zealand’s Protestant churches from the early nineteenth century up to World War II.
