Originally, it was planned to do the audit last week.
Maritime New Zealand senior media adviser Sophie Hazelhurst said Mad Dog would be tested against Maritime New Zealand guidelines standards.
"Operators have been aware of the guidelines since last year and started working towards them last summer.
"Part of Maritime's role is to lead and support, so they will be talking to the operators and allaying their fears about what they should be doing," Ms Hazelhurst said.
The review would "take as long as it takes".
"They'll be talking to different operators and . . . they will have different issues they need to address."
Black Sheep Adventures Ltd, Mad Dog's parent company, and its director, Brad McLeod, admitted Health and Safety Act charges relating to the death of English tourist Emily Jordan (21).
Ms Jordan drowned after being caught between submerged rocks while riverboarding with Mad Dog on the Kawarau River on April 29 last year.
Black Sheep Adventures was fined $66,000 and ordered to pay $80,000 in reparation to Ms Jordan's family after admitting two charges.
Prime Minister John Key recently announced a government investigation into adventure tourism industry safety standards, to be led by Labour Minister Kate Wilkinson, which would investigate how the industry managed risk, in light of accidents and deaths in the sector.
Mad Dog has also applied for a new resource consent to operate on the Kawarau River, seeking a land-use consent to use the Kawarau River from the Arrow River confluence to the boundary of the Queenstown Lakes district at the Roaring Meg power station.
Last week, Mr McLeod announced he had voluntarily suspended operations until Maritime's audit was complete and was seeking an external audit by the Register of Outdoor Safety Auditors and an independent peer review by the rafting industry.
