Hi Bob,
I am researching the OMOND family descended from Thomas OMOND (1843 Eday, Orkney - 1911 Port Chalmers, NZ) and his wife Catherine MILLER.
So far I have failed to find the arrival in NZ of Thomas - he was in the census in Kirkwall in 1861 as a 17 year old ships carpenter; and must have arrived in NZ before 1872, as he was both married and purchased land at Lower Harbour that year.
Have you come across any OMOND arrivals?
In my searching I have found this that may interest you - I found it on the Papers Past website [https://paperspast.natlib.govt.nz]:
Marriage: On the 26th January 1882, at the residence of the bride’s parents, Elgin House, Cumberland street, by the Rev Dr Stuart, Peter Spence, eldest son of Mr Peter Omand, to Susannah Farnley-Bowie, youngest daughter of Mr John Drew. [OTAGO WITNESS, ISSUE 1577, 4 FEBRUARY 1882]
Sincerely,
Pip
