Thanks to all who tried to help with this. The mystery is now solved. I
noticed a post about the corn marigold in alt.binaries.pictures.gardens and
thought it looked very familiar and, to cut a long story short, a little
quick research established that Chrysanthemum segetum is the identity of my
mystery plant. So yet another Mediterranean plant has established itself in
this corner of the Southern Hemisphere.

Does anyone have any ideas what this daisy may be?

It's a subshrub or evergreen perennial around 40-50cm high, the
flowerheads
are up 5cm diameter and I photographed it today, which is midwinter here
in
New Zealand. It's been flowering for several months and shows no sign of
stopping. The garden is in a frost-free area.
