absolutely stunning flower, x10 better than last year - it's pink! Since when were they pink?

About 10cm from last years observations: https://inaturalist.nz/observations/93238742), but only one flower found (plus one stem without a flower), whereas there were several in a 30cm² area last year.

The purple pictures are an (unplanned) attempt at using a UV light Tim Park happened to have. Perhaps I'll try UV again next time with better equipment.
