Ho do I find the emial address of someone in Parnell, Auckland, New Zealand

I am trying to find the email address of the Felix family who lives on Laruie Ave in Parnell and their son, Michael Felix who probably lives in the Auckland area. Their parents, aunts, and uncles and I spent about 50 years doing their genealogy. Now they have all passed on except one who is very old. They asked that I pass this work onto their descendants in Auckland. There is a 1 1/2 page introduction and a separate 7 MB essay of photos, narrative charts, and genealogy. I am open to alternative suggestions or assistance. I will attempt to paste the introduction below.

Thank you for any assistance.
