skinkysam's Identifications

Struggling to identify this beautiful plain green gecko from current literature unless it's N. elegans well out of known territory. It had virtually no markings apart from the visible tiny patches of white spotting.
It wasn't interested in hanging about for a better portrait. Can anyone help please.
I have seen similar but with a few white patterns, presumably N. stellata, in 2015, but too shy and wary to get photos.

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.

Skink #3
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 shorter of the 2 (the one on the left in the yellow bucket).
I didn't measure this one. It looked quite fat - pregnant? Just had a big meal?

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.

Skink #4
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 longer of the 2 (the one on the right in the yellow bucket).

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.

Skink #1
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 smaller of the 2 (the one on the left in the yellow bucket). It was about 9.5cm long, give or take a little.

Found two of these while clearing an area of overgrown suburban backyard - mostly Tradescantia with lots of wood and other debris under it, beneath a tall mixed canopy of natives and exotics. Seemed good habitat that could potentially have held a lot more, but nice to know the species is still holding on so close to central Auckland.
