Police are appealing for sightings of a silver car in connection to the disappearance of Christchurch man two months ago.
Michael McGrath was last seen at his home in the suburb of Halswell on 21 May, about 4.30pm.
Police want to hear from anyone who saw a late 1990s silver Toyota Camry in the Halswell area, or greater Christchurch area, in the two days after Mr McGrath went missing.
Officers said they had found a number of items of interest during their four-week search of the Kate Valley refuse centre.
Those items are being examined further and police said they were continuing to analyse CCTV footage gathered as part of their investigation.
