GARDEN gnomes gathering at the board-walk section of the Dunes Trail is so far a bit of a mystery.

Opotiki residents have expressed bemusement over the silent and stationary creatures, who seem to increase in number over time.

Motu Trails executive officer Jim Robinson said it was “probably someone having a bit of fun”.

“I wouldn’t have a clue. I don’t know who’s been doing this,” he said.
