There are concerns for the welfare of a missing German tramper who has not been heard from since Tuesday.
Esther Gehrmann, in her early 40s, was believed to be tramping in the Mt Starveall area of the Mt Richmond Ranges in south Marlborough, which was part of the Te Araroa Trail.
Ms Gehrmann left a message in the Mt Starveall hut log on Tuesday, the content of which had raised concerns for her welfare, police said.
The alarm was raised yesterday evening by a tramper who had been in the area.
It was believed she had intended to walk south towards St Arnaud, police said.
Nobody had reported seeing Ms Gehrmann on the track or at huts.
Police would like to speak to anyone who had been in that area and anyone who had spoken with her.
Anyone with information should call Nelson police on 03 5463840.
