Livery: |
The 36 feet high funnel, originally Buff, was repainted Red with a Black top in July 1959, as the former light colour soon became smoke-stained. The colour was changed again in June 1962 to light Stone with a Black cap, to conform to the livery adopted for the new Wellington-Picton ferry Aramoana; monograms were added with the letters NZR in Yellow on a Green background on both sides of the funnel. |
