DSJ 4004 was also accidentally driven off the end of the linkspan at the Picton port, where she sank to the bottom of the harbour. She was floated to the surface with airbags and lifted out with a 300t crane and sent to I believe Hutt shops. Due to the extensive water damage and the impact at the bottom of the harbour, DSJ 4004 was written off and used as a source of spare parts for the remaining 4 units
