Skirts New Zealand shrubs (5)
I believe the answer is:
tutus
'skirts' is the definition.
(tutu is a kind of skirt)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tutus that I've seen before include "Certain dance outfits" , "Ballet costumes" , "Ballerinas' short skirts" , "Ballet dresses" , "Ballet skirts" .)
