There is a marriage entry in the NZ BDM to confirm the details on the previous reply.
1926/6214 Emma Doris Margaret Corcoran married George Stephen Whibley
and death records to match:
1973/49078 Whibley Emma Doris Margarette 21 September 1873
1950/28429 Whibley George Stephen 73Y
Looks like Emma made it to 100yrs, or very nearly.
And further confirmation if necessary, on the 1935 census you can see Emmas daughter, Una Gladys Marion Corcoran, living in the small place in the Waikato as Emma and George.
