Dairy industry figures show there was a big jump in milk production at the beginning of the season.
Production was up by a third in June, compared with the same month in 2010.
The NZX Dairy Trader service points out that June is the seasonal low point for milk production in New Zealand, so the strength at the start of the dairy season does not mean the increase will determine production throughout.
However, it says cold snaps aside the weather outlook for milk production remains favourable.
The MetService outlook for September and October is predicting normal or above normal temperatures, while soil temperatures and moisture levels are on track to promote pasture growth.
