I was taking a walk at the Auckland Domain the other day and out of no where a few of these birds plunged from the sky and gathered on the grass started looking for food. Their colours were so bright and eye catching. I did a quick lens swap, pulled out my 70-300mm and started following them. I can tell you 70-300mm may sound like a very long lens, but it was still too short for catching Parakeets like these. Even with my crop factor of 1.5. They were shy. I had to get low onto the ground and moved inch by inch commando style to get closer. This was the closest i got to one of them.
Pukekos are easier to get close to. They tend to be less shy. There is a wetland across the road from where i stay. I see Pukekos feeding there everyday.
