Well more wealth of information at Papers Past.
The Thames Star and Ohinemuri Gazette have published lists of names for reservists and others who enlisted.
Lists of Reservists were drawn up by ballot under the Military Service Act of 1916.
I found that good search words were BALLOT and HAURAKI also "CALLED TO THE COLOURS"
There are over 15 Ballots that I have found, so unless someone wants all of them I'll post a couple
Ballot one published 25 Nov 1916, 15th Ballot published 25 april 1918
Others 24 July 1918 with lots of names
You can also see reports of the court cases where people asked to be left off the lists for family or occupation reasons.
