The New Zealand jet boating industry is made up of 42 operators carrying over 370,000 passengers a year.
There have been two fatalities in the commercial jet boating sector since 1999.
The Tourism Industry Association (TIA) said the mandatory driver licence will further strengthen the country's world class adventure tourism sector.
The Government's decision supports the work being done by TIA, the industry and other organisations to ensure tourism operators run a safe operation, said recently appointed chief executive Martin Snedden.
Snedden said the TIA is working closely with operators across the wider adventure tourism sector to strengthen safety systems and management.
"It's critical that 'adventure' remains in adventure tourism, but the industry has a responsibility to ensure that these experiences are being delivered within a strong safety framework."
The rule also makes driver log books mandatory, and includes design and construction changes, such as emergency exits and footrests, that provide greater passenger protection.
