The Post reports:Colin McCahon, Goldie, Don Binney: Impoverished councils around New Zealand are sitting on a $1.1 billion art goldmine, much of it unseen by public eyes. But I was staggered that the total value of art owned by councils is over $1 billion. Also the vast majority of the art is not available to the public. In Auckland the art gallery can only display 2.4% of its collection at a time. It is worth remembering this when Councils claim they need massive rates increases to fund critical infrastructure.
