This is the family headed by a David, coal merchant, that I referred to earlier and I am pretty confident originally from the family found by Joe in 1841:
David Waldie 35, coal merchant, b. North Leith
Margaret Waldie 22, b. Ayr
Alex B Waldie 8
James P Waldie 7
Wm Blackwood Waldie 3
Elizabeth G Banter 17, servant
Margaret Glass 22, servant
Address: 6 Grove St, Edinburgh St Cuthberts
These are the birth of the children showing to David and Margaret Blackwood on IGI:
1. ALEXANDER BLACKWOOD WALDIE Birth: 27 APR 1862 Edinburgh, Midlothian, Scotland
2. JAMES PATERSON WALDIE Birth: 09 FEB 1864 Edinburgh Parish, Edinburgh, Midlothian, Scotland
3. DAVID WALDIE Birth: 19 FEB 1866 Edinburgh Parish, Edinburgh, Midlothian, Scotland
4. WILLIAM BLACKWOOD WALDIE Birth: 04 JUL 1867 Edinburgh Parish, Edinburgh, Midlothian, Scotland
5. MARGARET MC LEAN WALDIE Birth: 25 JUN 1872 Edinburgh, Midlothian, Scotland
Karen, the problem we have here is one of verification. There is no entry showing for a James (William) Waldie b. 1855 +/- 2yrs, and none with a father David in that period where the father has an occupation related to the coal industry.
The only ones showing on the later censuses are either the family above headed by a David or the family headed by a James that I posted earlier. Both their sons called James look to have been born in the early 1860s.
Without some form of verification from NZ documents, it is hard to be more definite.
Regards.
