"The centrepiece is Long Hee Lee, the image focuses on the theme of regeneration."
The Beech at Ohau series of 11 monoprints highlights the melancholy beauty of the surviving beech forests.
Cooke says she has used the mediums of ink, canvas and paper to focus the audience's attention on protecting New Zealand's small and ever-diminishing indigenous forest stock.
"There was a time, in Aotearoa, when early European settlers' children could not hear their teachers in the schoolroom due to the deafening sound of the indigenous birdsong.
"The birds thrived in an ecosystem of mature forest lorded by the ancient columns and canopies of kauri, beech, rimu and totara giants."
The artist says the exhibition is also about climate change which is closely linked to deforestation and is the issue of our times.
"Kauri dieback is another side effect and a particular issue that requires New Zealanders to take action."
