Decent colony sheltering in Agave americana
Looks like D facetus to me but I could be wrong given only observations are in Northland.
Under bridge (suitably trollish)
In ?Yucca, again with Cambridgea (third photo)
In Arthropodium patch alongside Cambridgea (last photo). Spider photo itself didn't work out well!
Absolutely enormous colony that has encased an entire shrub
Again occupying the same plants as Cambridgea
Common in dense vegetation — often the same sort of vegetation occupied by Cambridgea (see last photo for sheetweb in same plant)
Decent little colony off side of decrepit boardwalk
Almost certainly Dolomedes minor
Found at Yarrs lagoon
