Another cyberattack on its parent company Lion affected operations at Speight’s Brewery in Dunedin last week.
Last Thursday, Lion was the target of a second cyberattack in the form of ransomware, where computer hackers seize control of data or systems then demand a ransom that often runs into millions of dollars.
A Lion spokeswoman said that Speight’s Brewery was only partially operational last week.
"It’s difficult to put a percentage figure on the exact level of operation," the spokeswoman said.
Lion and its cyber team continued to investigate the attack, which caused a partial IT outage, she said.
"The good news is we are now fully operational, brewing and kegging beer.
"We are very grateful for all the support we have received over the last week and the flexibility and understanding of our customers, suppliers and our people."
The first cyberattack, on June 8, halted brewing at the factory entirely, affecting supply and distribution.
