June 1967: Barometers were unusually high over New Zealand during June and it was a month of settled weather with comparatively low rainfall. Southerly winds were more frequent than usual, especially over the North Island, where temperatures were below normal. Most farmers found conditions very much to their liking, though in parts of Waikato, King Country and Bay of Plenty unusually frequent frosts greatly reduced growth.
Rainfall: Rainfall was less than half the average value over nearly the whole of the South Island and also over the greater part of the North Island. Greatest deficiencies were recorded in the Alps together with the Canterbury high country, and parts of Central Otago; also in most of North Otago and the Dunedin district. In all these areas rainfall was less than 1/4 of the average value. The only district with rainfall above average was Hawkes Bay, where 2/3 of the total fell on the 3rd and 4th. This was the driest June over the country as a whole since 1958. However, in the South Island, June 1964 was drier than either June 1958 or June 1967.
Temperatures: In the North Island temperatures were 1F-4F below average. Greatest departures were recorded in Auckland, Waikato, Waitomo, Taumarunui and Taupo; in these areas it was the coldest June for many years, but about equal with 1951. In the South Island temperatures were mainly close to or somewhat above average. On the 21st snow was reported in Southland to low levels and elsewhere well down on the ranges.
Sunshine: Sunshine was above average over the greater part of the country. Waikato, Waitomo, Canterbury and Westland were particularly favoured, with surpluses of 30-40 hours. By contrast, eastern districts of the North Island and Northland had less sun than usual, mainly by 30-40 hours.
