Skink #2
Found under a tyre being used to protect a young tree from hare damage.
There were 2 skinks under the tyre, and this observation is for the larger of the 2 (the one on the right in the yellow bucket). It was 12.5cm long (approx - it was also wiggly and I didn't want to stress it more than I had to).

The other has been put as a separate observation: http://naturewatch.org.nz/observations/1696619/

After the photos were taken, mulch was put down under the tree, the tyre replaced back on top, and then the skinks were released back to the same spot.
