Larry McKenna, of Escarpment Vineyard in Martinborough, was also upbeat.
"We're loving it. Grapes love warm weather," he said.
Mr McKenna said that although dry weather was good for grapes, the weather was unusual and could change.
"It's February weather. It's very dry for this time of year. Since early December, we've had warm, dry weather.
"There are still the critical six weeks to run."
If the weather pattern holds, the wine industry looks set to have a good year.
"We are on track for a good harvest if the weather remains stable. We would expect a high quality fruit with good flavours. It should be very good.
"I couldn't be happier right now," Mr McKenna said.
John Kavanagh, chief winemaker at Te Kairanga wines in Martinborough, is also optimistic.
"It's too early to call, but this year is tracking in the right direction for a really good vintage," he said.
"It's great at the moment, this long dry period is exactly what a grape grower wants."
The optimism isn't limited to Martinborough.
Jane Cooper, general manager and chief winemaker at Matahiwi Wines in Masterton, said: "The season's shaping up really nicely. Growth is really good. We're pretty happy really."
She hopes the settled weather continues, but acknowledges it's not good news for everyone and that some rain would be good for irrigation.
"What we need from now is warm, settled weather until harvest. Then the chances are it will be a really good vintage.
"I feel sorry for the farmers because it's super dry," she said.
