The search for a tramper who has been missing for a week continues today.

Allison "Ally" Willen was last seen on the Gillespie Pass track on April 25.

Police together with Land SAR volunteers would today continue the search for her.

The weather conditions in the area are good.

The search is being conducted by air, foot and river searches.

Miss Willen had been studying at Otago University for a short time on an International Studies Abroad programme and was tramping with two other female friends from the university - from whom she became separated - when she went missing.

An extensive two-day search effort focused on the Young River, where items of clothing and her backpack were found in the river.
