This is the small brown blowfly that's the common fly dead at the base of our house windows at the moment. I keyed it out using the 1954 key I found at http://rsnz.natlib.govt.nz/volume/rsnz_82/rsnz_82_03_008400.html. It mentions two golden brown blowfly species in New Zealand, Calliphora rufipesCalliphora hilli and Calliphora stygia, which are separated by their number of pairs of presutural aurostichal bristles. I had to look that up on Google, then counted two pairs (annotated on one of my photos) which match Calliphora rufipesCalliphora hilli. Calliphora stygia has three pairs.
