Thousands of motorists in West Auckland were breath-tested for alcohol over the weekend as part of a police blitz to make sure people are not drink-driving during the Rugby World Cup.
More than 4300 people were stopped at checkpoints in and around Henderson and New Lynn on Thursday, Friday and Saturday nights to check their alcohol levels.
A total of 43 drivers were found to be over the limit.
Of those people, 20 drivers were over the new lower limit of 250mcg with recorded levels between 250 - 400mcg.
While 23 drivers were discovered to be more than 400mcg over the limit and were now facing criminal charges in relation to driving with excess breath alcohol.
