Not a bad one here either on -4.1deg. 20+ years ago we would have much colder than Christchurch Airport.

Only down to -1C in the Botanic Gardens. Could the airport calibration be off?

I would say not, many of the private weather stations in around CHCH were around -4 also, central city temps are effected by urban heat sink

I understood the NIWA one in Riccarton was susceptible to urban heat, but had thought (until now anyway) that the Botanic Gardens location was to negate that.
