Hubert Thomas "Tim" Armstrong was a New Zealand politician in the Labour Party.

The Lyttelton Harbour Board was established on 10 January 1877 to manage Lyttelton Harbour. The harbour had previously been managed by the Canterbury Provincial Council, but provincial government ceased to exist on 1 January 1877. The harbour board was governed by members elected during local elections. Lyttelton Harbour Board was disestablished through the 1989 local government reforms, with its functions transferred to the Lyttelton Port Company.
