The traffic control box beside Heron Park is another one of those difficult-to-photograph ones. Mainly because it's on the busy intersection of Great North and Blockhouse Bay Roads. There is always a risk of getting in the way of traffic taking an image of this piece of art.
Still, I'm glad it's there, and reminds people (hopefully!) that Heron Park on the Avondale-Waterview border is named after the bird, and not some Mr. Heron.
Update, 14 January 2011: On 5 December 2010, the box was replaced as part of an upgrade by a larger box, and the art is gone. See comments below.
