Abstract Six species are reported as additional or newly substantiated fully naturalised records for the flora of New Zealand during the 2-year period 1999–2000. Seventy-one species are considered to be new records of casual naturalised plants. Thirty-five additional species that were previously known from few collections are given extended distributions. A list is also provided of fully naturalised taxa that have made significant range expansions, e.g., were previously known from only one of the main New Zealand islands, but which now occur on the other island. For a number of taxa discussion is presented on their indigenous or naturalised status.

Keywords naturalised flora; weeds; dicotyledons; pteridophytes; gymnosperms; first records; distributions; New Zealand flora
