Can anyone help me with details of these tennis events played in Queenstown?

My name is Cristian Uguzzoni and I am writing from Italy. I am looking for information regarding a couple of tennis events played in Queenstown.

1. 26-31 Oct 1957. Players involved : Pancho Segura, Ken Rosewall, Lew Hoad, Jack Kramer. 
2. 13-18 Oct 1963. Players involved : Rod Laver, Luis Ayala, Alex Olmedo.

Does anyone have any details, copies of old newspapers etc.? Any kind of help will be greatly appreciated.
