These are the churches that close to you http://yellow.co.nz/whitepages/search/Auckland+CBD/church-1.html
Over the last 15 years I have seen so many Chinese immigrants going to churches and made good loyal friends. When you have more local friends you have more chances to become success and living in New Zealand is more enjoyable.
Remember NZ is one of the easiest countries to live in the world. If you are clever and not too lazy you should be able to survive in NZ.
