The first rail-ferry flag is yellow with narrow green stripes near the top and bottom. Between them is a green-outlined shield or badge with green NZR, the Z larger. Its relative height differs between Brown and The Log; the drawing follows Aramoana’s funnel.
N17 was adopted in June 1970. Arahunga photographs and the Arahunga and Aratika models confirm its framed funnel panel from both sides. The flag’s lower panel was initially seen as almost-black dark blue, then judged black; Rosanoski bases it on an actual held flag. He identifies N668 as reversed.
NZR correspondence dates this funnel to 1985, with Arahunga and Aratika repainted that April, though The Log instead gives June 1984 for Aratika. Arahua carried it from construction. A model’s white funnel base, which would make the band white-black, is treated as an unrealised proposal or modelling error; a January 1987 photograph confirms a light-yellow base.
