Police in Dunedin are trying to track down the owner of what appear to be valuable stamp collections.
The two collections have been with police for three years after being found at a Dunedin house.
Senior Sergeant Craig Brown says they have never had any inquiries about the stamps during this time.
Mr Brown says one album includes First Day Covers addressed to a couple who possibly lived in the Lower Hutt or Trentham areas and dates back to the 1940s.
The second is a black covered Flying Eagle brand album.
