Bo Wang was stopped and tested on 24 July after leaving a central Auckland bar.
Wang’s evidential breath test showed he was twice the limit. He requested a blood test.
Later that morning he gained entry into a police facility using a colleague’s swipe card, took his blood samples back to his home, and flushed them down the toilet. The destruction of the samples meant he could not be charged.
Wang, who has resigned from the police, previously admitted charges of perverting the course of justice and burglary.
At sentencing today in the Waitakere District Court he was sentenced to eight months home detention. Police had sought a prison sentence but this was declined by the judge on the basis of Wang’s previous good character and early guilty pleas.
