A pregnant woman has been robbed at knifepoint while on a bush walk in west Auckland.
Police say she was walking on a Waitakere Falls track close to the Piha Road carpark about 10.45am on Tuesday.
They say two men with their faces covered emerged from the bush, one of them holding a knife. They fled after taking the woman's necklace, rings, bracelet and watch and have not been found.
The woman, who is five months pregnant, was not physically harmed but was taken to hospital for a precautionary check-up.
