Is there a registry of Church of England clergy in NZ available.
There is a Church of England clergy book that spans many countries . It is published every couple of yrs and certainly goes back beyond the period of interest to you.
It is called CROCKFORD and most large public libraries in their reference section should hold runs of it.
I'd suggest you phone your largest accessible public library and ask the reference librarian if they have Crockford for the approximate time frame you want and would they look up the clergyman's surname for you. If the entry is there it will summarise the parishes in which he has served, dates of incumbency and so on.
If the public library approach fails, then a Church Of England Theological College Library would most likley have these or could tell you where to go.
Another alternative is to post on RC and ask for CROCKFORD lookup of the minister you want. I can't remember how the surnames ar organised- whether it is just straight alphabetical or by diocese or by country.
This is how I have gone about finding a clergman in the past ..
hope it works,
