Auckland Mayor John Banks, a candidate for the mayoralty of the proposed Super City, has been uncharacteristically modest about his efforts to rescue a cat in a tree.

It is understood the kitten was part of a stray cat colony in Dove-Myer Robinson Park, Parnell, where Mr Banks is known to feed the animals.

He got a call late on Wednesday night from a constituent about the kitten's plight and spent about two hours yesterday morning helping to rescue the animal.

But later, Mr Banks said he didn't want to talk about it.

"I love cats. I am an animal rights activist. Thank you very much for the call. There is nothing more to say.

"I change light bulbs for elderly people, I unblock drains and I rescue cats.

"It is part of being the mayor of a super city. That is all I want to tell you. Have a great day."
