Hi Jahall,
There is a probate held in NZ for Olive....
www.archway.archives.govt.nzSMITH Olive Margaret - Whitford - Married Woman
1944 High Court Auckland, Department of Justice Akld
You will have to ask nicely if someone in Auckland can go and look for it or contact Archives NZ and pay for the photocopy. No guarantee of how much info it will have in it for what is charged for the copy but you may find other family listed either in NZ or England.
And this could be her husband:
SMITH Frank Edward - Auckland - Retired Farmer
1976 High Court Auckland, Department of Justice Akld
Also held in Auckland Archives. Sorry I can't help as I'm in Wellington

And the place name in the marriage cert would be Tokomaru Bay and here's something about that place:
Tokomaru Bay is a bay and town located in the remote East Cape (Gisborne) region of New Zealand’s North Island, 100 km (60 miles) northeast of Gisborne city and close to Mount Hikurangi.
The seven-kilometre wide bay is small but sheltered, and was a calling place for passenger ships until the early 20th century. Captain Cook spent time here on his 1769 journey of discovery, and later European settlement included a whaling station.
The area around the bay has long been a Maori stronghold. The nearby pa at Te Mawhai was refortified during the battles between colonials and Maori in the 1860s.
The town's modern prosperity derives mainly from agriculture and forestry, with some tourism. Its population is predominantly Maori, with the area being a stronghold of the Ngati Porou iwi. The bay's name is taken from that of a traditional waka (canoe).
Cheers
Bunny
