Toast Martinborough organisers extended their best wishes to the woman and chairman Richard Riddiford said they were delighted to hear her injuries were not serious.
"This was a terrible conclusion to what had probably been a fantastic day among the vines, and we wish her a speedy recovery.''
Meanwhile, three drunk drivers were arrested leaving Toast Martinborough yesterday, including one who had a breath alcohol reading more than three times the limit.
Ms Watson said police stopped 398 people at a Ponatahi Rd checkpoint as they left the food and wine festival.
A Masterton man in his 40s was caught with a breath alcohol limit of 1405mcg at the checkpoint - the limit is 400 - and Ms Watson said he was "pretty hammered''.
