The private search for missing Israeli tourist Liat Okin will continue on and around Fiordland's Routeburn Track.

Search party spokesman Shai Lanuel said today reports the search was being called off were false, and friends, family and volunteers would continue to look for the missing 35-year-old today.

The group would reassess the situation tomorrow, he said.

Ms Okin was last seen at the Mackenzie Hut on the Routeburn Track on March 26.

A police search failed to find any trace of her and a private search co-ordinated by her brother, Itamar Tas, was launched on April 24.

Mr Tas said this week he remained hopeful of finding his sister alive despite the being missing for nearly two months.
