Looking for Mabel Catherine Whisker

Mabel Catherine Whisker was born in 1907 at TokaToka, Northland, NZ
Her Father was James Beattie Whisker (born 1870, died 1954)
Her Mother was Margaret Annie Caisley (born 1884 died 1956)

Apart from her parents the only other information I have is from the 1935 NZ electoral Roll which shows a listing for a Mabel Catherine Whisker living at 152 Rutene Road, Gisborne, Occupation Spinster)

Hoping someone out there knows a bit more.
