Gisborne region's grain maize harvesters were between 40 and just over 50 per cent of the way through their season by the end of last week as they enjoy perfect harvest conditions.
Corson Grain procurement manager Richard Hyland said the season had been excellent so far.
"We are well ahead of schedule and just over half way through our harvest."
"Yields are well above average and the maize quality is good."
Corsons has been harvesting at all three of its growing locations — Tolaga Bay, Gisborne and Wairoa.
