"It's a bit tight [for staff numbers], putting it mildly.''
The early season for fruitgrowers was exacerbating the staff situation, and vineyards were competing with orchardists, who also needed staff earlier than usual, Mr Dicey said.
The cherry season is also early, and apricots in a Cromwell orchard were picked in November for the first time in its 103-year history.
Mr Dicey said the warm weather would mean not only an early season but a longer season, which could translate to higher quality grapes and higher yields. But he did not want to pre-empt a "bumper'' season.
"You'll never get a comment from me saying that. We need to wait until the grapes are picked and the wine's in the bottles before we can talk about that.''
Vineyard staff were still finishing wire lifting and also beginning shoot thinning and bud rubbing. They would also have "a month of ridiculous levels of tractor work'', doing things such as crop spraying and mowing, Mr Dicey said.
The Central Otago harvest normally begins in the third week of March, but growers were preparing for it to begin in the first or second week of March, he said.
