Kiwi kids have flooded an Auckland environmentalist's mailbox with droves of paper monarch butterflies for an art installation marking the Moths and Butterflies Trust of New Zealand's 10th anniversary.
The artwork is to be installed at the gala premiere of the movie Flight of the Butterflies, at Hoyts Sylvia Park on Monday.
The film followed the year-long annual migration cycle of the butterflies and showed millions of monarchs in their overwintering sanctuaries in Mexico.
Trust secretary Jacqui Knight said thousands of kids had sent in paper butterflies in all shapes and forms for the artwork.
"Mostly brightly orange coloured, but in all sorts of media, some with glitter on their wings."
