Maori motif on Grecian urn

On my back from work this afternoon, I needed to pause by the central railway station. Not the old one which is now cheap(ish) apartments. The new one which will end up being the centre o& an underground central city rail loop. To get some cash from the ATM. 

Nearby is the Hotel Britomart. On the northwestern end wall of that building is a collection of paintings, each appearing to depict a painted Grecian urn. Most with a Maori motif. My blip shows the one I liked most.
