Some Hawke's Bay vineyards have not been harvested at all this year due to the wet weather in recent weeks, but winegrowers are confident that the fruit that has been picked is of a high standard.
Hawke's Bay winegrowers chairman and Trinity Hill chief executive Michael Henley said he could not put a number on those who were most badly affected but that most growers had taken a hit to some extent.
"People have had their crops declined because they did not get to the level some companies wanted.
"At Trinity Hill we have lost some harvested fruit but you just have to take it on the chin and hope next year is different."
He added that the situation was not as bad as in 2012 when it never got warm during the summer months.
