The Serious Crash Unit from Whangarei is investigating both incidents, Kaitaia's senior police officer, Senior Sergeant Geoff Ryan, saying it had not yet been determined where fault lay in regarding what happened in North Road.
Drunk pedestrians on any road were always placing themselves in significant danger, he added, and all such incidents were given the highest priority by police.
His staff had dealt with one such incident early on Sunday afternoon, when a 43-year-old woman, described as highly intoxicated, was found walking along the Awanui Straight. Police delivered her to her daughter.
"It goes without saying that people who are affected by alcohol should keep well clear of roads, especially busy ones and especially at night," Senior Sergeant Ryan added.
"There is always a very high risk of serious injury or death, particularly at night when motorists can have real difficulty seeing them."
