Bay mother Tracey O'Brien will be farewelled next Monday at a funeral service at Omokoroa Community Church followed by a private cremation.
Ms O'Brien, 26, was killed when her silver Nissan Coupe crossed the centreline and collided with a people mover on State Highway 2 at Te Puna on Saturday.
Her children, Faith, 3, and Phoenix, 4, who were injured in the crash, remained in high-dependency wards at Starship Hospital.
Their father Matt Ruddell, 27, said his children were awake and in a stable condition.
Faith suffered bruising to her brain, he said.
