A Christchurch ute carrying potentially dangerous radioactive material is still missing.
The white Ford Courier, registration WM1511, was reported stolen from New Brighton on Tuesday.
The ute was marked 'Class 7 radioactive' and was carrying a nuclear density meter.
The meter had two small radioactive sources, with the material encapsulated in stainless steal.
A police spokesman said the ute and the radioactive material were still missing this morning.
Although the amount of radioactive material on the ute was relatively small, unauthorised removal of the radioactive material still posed a potential public health and safety concern, Inspector Marc Paynter said.
He appealed to the person who took the vehicle to "do the right thing" and tell police where the material was.
Anyone with any information is urged to contact their nearest police station, or report information anonymously should call Crimestoppers on 0800 555 111.
