The Italian-built, 60-tonne, 24m-long, multimillion-dollar motorised supercruiser - owned by Mike Mahoney, of Wellington - was on its inaugural charter with a group of Chinese tourists, when it allegedly smashed into an X treme Fishing Charters boat.
X treme skipper Craig Hind declined to comment when contacted by the Otago Daily Times last week.
Mr Mahoney did not return calls made by the ODT yesterday.
MNZ was notified later that day, sparking an investigation that also includes allegations Pacific Jemm backed into the wharf at Walter Peak, damaging its stern.
MNZ media liaison Ross Henderson said the authority was looking at taking action against Pacific Jemm's operators "pending the outcome" of inquiries into the incidents.
"That is something we're looking into at the moment ... We are asking why they are operating without a Safe Ship Management certificate," Mr Henderson said.
A Safe Ship Management certificate is required to operate commercially in New Zealand.
However, yesterday Mr Henderson confirmed the vessel had been certified and "can now resume commercial operations" after certification issues were "resolved".
Certification was a "separate issue" from the alleged charter trip incidents, which were still under review, Mr Henderson said.
A decision on the incidents was expected shortly, he said.
