The Dunedin Heritage Light Rail Trust was formed with the aim of reinstating the Mornington cable car line. Currently (2018) four trustees serve, and they have the responsibility of planning the detail of how the service may be re-established, and of seeking the necessary funding.

The High Street Cable Car Society is a body formed to enable enthusiasts to support the project, and is open to public membership. An AGM is held in the latter part of the year.
