A motorist stopped in a West Auckland drink-driving blitz this weekend was so drunk she had to be taken to hospital, police say.

Senior Sergeant Regan James said the woman had to be taken to hospital by ambulance and had been charged with driving while incapable.

The woman was one of 95 people stopped in the blitz who were measured as driving with excess breath-alcohol.

Nine checkpoints were set up as part of the blitz, which ran from 8pm on Friday to 4am yesterday.
