Trevor Pitt, the police spokesperson, said the driver was breathalysed at more than double the legal limit after he had driven off the wharf, after midnight.
The rental car was pulled from the water using a crane.
Despite repeated warnings, Pitt said police officers once again had to respond to multiple incidents of drunken behaviour around Rarotonga.
“In terms of driver behaviour, one person was arrested following a collision at Betela, and charged with drunk-driving. A second person was also arrested for refusing to be tested for alcohol after her vehicle ended up in a stream at Vaimaanga.”
Also in the early hours of Saturday, two males were arrested and charged with assault, following separate incidents of fighting in the town area.
A further incident resulted a man being arrested by police, following a complaint of a female being assaulted.
Pitt says the consequences of drunken driving – from minor mishaps to the tragedy of a fatality – are the concern of the community as a whole as the costs continue to mount up, negatively impacting families year after year.
The police service is working with stakeholder agencies on curbing drink-driving under proposed new law changes. A new limit is on the agenda.
