Having now looked at the map the area seems to cover quite a large area which is why I missed the Northern Brown Argos which I'd hoped to see. The area I covered was around NZ329325 and I only managed a brief visit so more than likely missed quite a lot that can be seen in the area.

Also in the area I came across 2 species of orchid, Common Spotted which I've seen at several sites including Stags lodge though the plants do have a slightly different shape here than the ones I have seen before. The other orchid I found was the Chalk Fragrant-Orchid (Gymnadenia conopsea) the first time I have come across this orchid.
