A total of 156 charges have been laid.
They include various allegations, including labelling wine as a certain vintage when in fact the grapes came from another year, false statements over where the wines came from, selling blended wines as coming from one vineyard, and trying to destroy or hide winemaking records.
Wines in question have allegedly been exported to the UK, Japan, Fiji, Thailand, and Australia.
It's understood that there is no health risk involved with any of the wine, which was made for drinking and not cellaring. None of the wine concerned is currently available for sale in New Zealand.
An interim suppression order made by Judge Stephen O'Driscoll today covers the names and brands of wines, along with the source vineyards and complainants, and the identity of the whistleblower.
The firm, directors Berry, 36, and Moore, 43, and winemaker Cope, 42, an employee, were remanded without pleas to November 30.
New Zealand Winegrowers has been advised of the MPI prosecution. The allegations, it said, are believed to be a tiny fraction of the national harvests of 2012 and 2013.
"We have been informed about the matter and the allegations and we know that MPI has been investigating carefully for some time," said Jeffrey Clarke, New Zealand Winegrowers acting CEO.
"New Zealand wineries and grape growers are committed to the highest standards of product integrity and quality, and there are very good systems in place in New Zealand to ensure this. The investigation proves the systems in place work and it is appropriate that this matter is before the courts."
New Zealand Winegrowers is concerned about the allegations and given the importance of label integrity, support the process.
"The New Zealand wine industry is highly regarded around the world and we cannot let the alleged actions of one winery damage a reputation that we have all worked so hard to build", said Clarke.
