He admitted two charges of dishonest labelling, two of substituting wine for a dishonest purpose, being party to false applications for export eligibility approval, four charges of sale of non-compliant wine, seven charges of false application for export eligibility statement, six of false application for export eligibility approval, nine charges of exporting non-compliant wine, and five charges of making false applications for VI1 certificate for export.
One fraud charge says Berry made a false statement over 49,905-litres of 2013 sauvignon blanc. Another related to a false statement over 55,350-litres of 2012 sauvignon blanc.
Between July 2012 and January 2013, he sold 54,000-litres of "untraceable sauvignon blanc" that did not comply with wine laws.
Another 49 charges were dropped.
It involves thousands of litres having been exported to the UK, Ireland, Japan, Fiji, Thailand, and Australia.
The 38-year-old will be sentenced in September.
Berry hopes to make reparation payments ahead of sentencing by selling his house, defence counsel Allister Davis said.
Given his financial situation, Berry won't have sufficient funds to pay a fine as well, the lawyer said.
Justice David Gendall called for reports that would explore home detention or community detention.
The co-accused deny charges relating to them and are scheduled to stand trial on July 22.
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 is available in New Zealand.
An interim suppression order made earlier covers the names and brands of wines, along with the source vineyards and complainants, and the identity of the whistleblower.
