Wellingtonians are being urged not to panic about a mysterious lack of Kereru

Just three of the native birds have been spotted so far in the 2019 Great Kereru Count.

In recent years, Kereru sightings averaged 150 a day during the annual September initiative.

Greater Wellington's environmental monitoring officer Faline Drummond says they're not concerned yet.

She says she won't worry about it until a few more weeks, but if they haven't turned up by the end of September that would be very unusual.
