Today, the court heard that the company, the directors and the winemaker have pleaded not guilty to all 156 charges. They have elected trial by jury.
Memorandums filed to the court have also revealed that Southern Boundary Wines was placed in voluntary liquidation by shareholders' resolution on February 2.
A lawyer for the company has applied to have the charges dropped.
Judge Stephen O'Driscoll adjourned the case until May 9. MPI has until then to decide whether it will challenge the application.
The judge also told the parties to consider whether the case should move to the High Court given the trial would likely take a "significant period of time".
The charges 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 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.
