searching for birth father/NZ connection

I was born in UK in 1954, some details are known about my father but alas no name. He was born in UK but grew up in NZ where his Grandfather owned a clothing factory. He studied economics at a university, he had a good secratarial post in London when he met my mother June Saxby. He did not know of my birth. He was interested in Art and liked swimming. Does this ring any bells with anyone?
