Hi Beg
Too be honest I can't remember exactly what they were as it was in 2006 and because I wasn't interested in the foster brother I only made a mental note that I had found something on him. I am leaning towards them being the examination records.
Yes I know I should make clear notes of everything I have searched

but I am usually rushing to make the most out of the opportunity when it arises which is not often. I am leaning towards them being examination records.
What has sparked my interest in following this up again is that I made a quick visit to the Auckland Archives Thursday week ago just before attending a family funeral. I found the thing I went there for and found a couple of other interesting tidbits. Then it got me thinking about the school records again.
I think I have clearer understanding of what records schools created now than I did in 2006 so perhaps I need to revisit the whole Ellerslie thing again to make absolutely sure I haven't missed anything. Because I don't have any exact dates I am guessing about when he would have been there.
He was born in 1892 (his foster brother in 1888), his mother married in 1904 in Stratford and we believe her future husband did not want to raise another man's child so she took him back to Auckland and had him fostered. His Statement of Service for the Railways says his Education Qualification was Std 5, so if I remember correctly that would make him about twelve when he finished his schooling. So maybe you are right and he never went to that school, although family lore says he did. Unfortunately the funeral I attended in Auckland the other week was the last of my parents' generation, a daughter in law of my grandfather's.
Cheers
