Doesn't look like the Ngaio that grows in our yard... plus strongly toothed leaves...
There are lots of these bushes growing along the Lyttelton Side of Evan Pass road. The leaves and growth form don't match any of the six species suggested here, and it isn't in my Common Weeds of New Zealand book. Now I'm curious!
Distinctive white dots on leaves, and leaf arrangement. No flowers present today.
