May I suggest that while in New Zealand you make enquiries of the Dunedin Regional office of Archives New Zealand as you would probably like to obtain a copy of the Deeds Plan of Heaton Farm while it was owned by J. E. Black?
This can be ordered and is presented by Archives on an A3 sheet* or CD. As a student of your family history I am sure you would find this document well worth having.
The search for this can be done on line but assistance may be needed by staff to locate the Deed required.
*Not sure about this but it is twice the size of A4.
