I checked the NZ BDM index again and there is only one marriage for an Emily Augusta Barrett from 1900 up until the cut off for historical marriages (around 1933/early 1934, i.e. those that occurred 80 years or more ago).
No deaths for an Emily Augusta Barrett, so
Emily Augusta Wilkinson certainly looks to be the lady you are researching..............
