The fourth time capsule discovered in the ruins of buildings hit by the February earthquake in Christchurch has been opened.
The metal cylinder-shaped capsule, found during the demolition of the Hagley Hostel nurses' accommodation, contained a letter about the building and two newspapers.
The papers are dated 25 March, 1931 - the year of the devastating Napier earthquake.
The Canterbury District Health Board's chair, Bruce Matheson, says the design of the hostel was changed as a result of the Napier quake.
Mr Matheson says the DHB was aware of the time capsule's existence, as the people who placed it left a letter describing its location, beneath the hostel's foundation stone.
The other three time capsules found since February's quake were under the damaged statue of John Robert Godley in Cathedral Square, and in the former Civic Building on Manchester Street.
They contained newspapers and council documents.
