Broke from the ANZUS defence treaty, and banned any nuclear powered ship from docking (ie. most of the US Navy). There were serious economic consequences and Regan considered a trade blockade, but got distracted and forgot. New Zealand has maintained a west-sympathetic but independent foreign policy ever since.
Australia tried something a bit more modest in the 70s, but we're an important anti-China staging ground, and we got stamped on and soft couped. New Zealand was just small enough and far away enough to escape.
