Interislander retained this funnel through the 1995–96 ownership and identity changes. Aratere’s port view of January 1999 and Aratika’s starboard view of October 1997 show mirrored emblems pointing forward. The design places a white stylised dolphin, with a blue line through its centre, between green and blue representing hills and sea.
Rosanoski photographed this flag in a Wellington railway-station display case on 4 February 2003. He never saw it flown; it disappeared from view after the travel office closed.
Following the Toll takeover, Arahua introduced this blue, green and yellow funnel after refurbishment in September 2004. Photographs of both sides on 5 October show the upper form continuing round the front in two green, shallow waves before resuming reversed on the other side. Four lower forms continue as a single shallow V-shaped wave. Another light-blue form may lie at the base, mostly hidden by lifeboats. The ferries retained these colours after the 2008 Government buyback; Rosanoski had seen no new flag.
