Intrauterine devices (IUDs) were introduced into New Zealand in the mid-1960s. Small pieces of plastic with copper wire wrapped around them, they work mainly by preventing sperm from fertilising an egg. The loop-shaped ones (Lippes loops) were withdrawn from the New Zealand market in 1985. The T-shaped ones (Nova-T devices) were introduced in the 1970s and used through the 1980s, but are no longer available. IUDs were still used in the early 2000s.
