Did your relative wear the Bonnet or the Cap? If yes, then their publication 'War Cry' might contain information. And accounts of their missions to towns around New Zealand might also contain information on the people they encountered. War Cry began in 1883 and has been indexed 1883 - 1919.
Lady Barker's book mentioned that at Ohau near Palmerston North, the Army Mission converted all the families except for one stubborn Catholic family. I took note because it was probably my Catholic family.
Did you have a relative in one of their Children's Homes? Residents have been recorded but the records only start at 1915 although the Homes began in 1900.
They also ran homes such as Hodderville Home near Waotu, Putaruru. A farm of 2350ac where boys 12-19 came as assisted immigrants in the 1920's. (see The War Cry 27th Jan 1934). Another was the Public Schoolboys Scheme.

No plans are in the air for putting their records online yet but they may do in the future.
