I even went to check up on the haumoana bird when Eric was with the new bird so we can confirm two birds.
This one was dancing quite a bit on the shallows and had a bright yellow face followed by a darker bill than the haumoana bird.
Will upload a photo soon.
Hopefully two birds meet up

the little egret was seen today along with 2 bittern, the egret was joining in the spoonbill group at the lake behind waitangi
