Theme shows are back. The Rotorua Museum of Art and History kicked off the season with The Mantle of water and, yes, there is a water work (Hotere Culbert’s “immense” Backwater), Fish/sea creatures (Elizabeth Thomson’s “dazzling” wall installation), rivers (Anne Noble’s “celebrated” Wanganui series), McCahon (gotta be a waterfall) and rain (Brian Brake’s “celebrated” Monsoon). You can catch the show, curated by ex Te Papa staffer Ian Wedde, until 5 April.
