It should be noted that in this list (only a partial selection of sites) the stations using manual equipment (Campbell-Stokes sunshine recorders) - Wellington, Christchurch and Nelson - are usually at a disadvantage to the electronic ones, which generally give significantly higher readings, especially in the early phases of use by the latter. The former include Wellington, Nelson, Christchurch.

Record high for Ch'ch; the Blenheim figure is not far above average and I suspect there may be issues at the site.
