People walking the Routeburn track need nappies (diapers) for the trip, according to bogus, yet realistic, Department of Conservation signs. Printed on cardboard in the familiar colors, the signs bear even the authentic department and Great Walks logos.
But that is where the similarities end, with messages advising people to wear nappies and directing people to a public toilet up a steep rock face.
One sign found on the Routeburn in September reads: "Please do not defecate in our National Parks. Heavy duty tramping nappies are available from all DOC visitor centers free of charge, and DOC hut wardens carry an emergency supply. Toilets in conservation areas are strictly for urination only."
