The search is continuing for an Invercargill woman who appeared to be under attack on a city walking track.

Witnesses have reported a woman was attacked by two people on the Estuary track around 6:15 last evening.

She was wearing a dark hoodie, yoga pants and was walking a young dog, that appeared to be a German Shepard.

Police want to hear from anyone in the area at the time, and speak to the woman to ensure she's safe and well.
