Looks like D facetus to me but I could be wrong given only observations are in Northland.
In Arthropodium patch alongside Cambridgea (last photo). Spider photo itself didn't work out well!
Absolutely enormous colony that has encased an entire shrub
The photo is a screenshot of a little video recording taken by friends.
Common in dense vegetation — often the same sort of vegetation occupied by Cambridgea (see last photo for sheetweb in same plant)
Almost certainly Dolomedes minor
