It took a "belligerent" and "grossly intoxicated" Waikato driver, who was four times over the legal limit, 19 attempts to complete a breath test.
The man was only one of more than 36 drivers Waikato Police said they tested across the region over the weekend, one they said kept them busy with both drink drivers and speedsters.
Several more drivers were also awaiting the results of blood alcohol tests, District Road Policing Manager, Inspector Freda Grace said.
On Saturday morning police were called to the scene of a crash on Pencarrow Rd in Tamahere shortly before 8am, Mrs Grace said.
"Here, a grossly intoxicated and belligerent man took up considerable police time, requiring 19 attempts to complete a breath screening test for which he returned a result of 1113 micrograms."
