This looks like Michael’s death registration.
1877 Auckland OND quarter 10a 118
Michael Rutherford Aged 45
This is very odd. He is exactly the right age in exactly the right District (and there do not seem to be any others of the same name on the censuses) which gives every indication that this was the husband of Margaret.
However, if it was, where did Margt (and possibly Mary) come from ??
