The first abortion clinic in New Zealand was the Auckland Medical Aid Centre (AMAC), which opened in 1974 and introduced the practice of vacuum aspiration to New Zealand. By the end of its first year, it had provided 2,288 women with abortions. By 1975, this figure had risen to 4,005. AMAC attracted opposition from anti-abortion activists including arson attacks. The New Zealand Police also raided AMAC in 1974, leading to the prosecution and acquittal of one of its doctors, Jim Woolnough.
