He said the slip happened around 8.30pm and covered both lanes. A crew from Downer was on site within 30 minutes to start clearing the road. Debris was pushed to the sides and then cleared yesterday.
Lee Thompson and her husband Aart Jansen managed to squeeze past the slip as they returned home to Rotorua from a trip to Auckland.
"We saw a huge slip that took out both lanes," she said.
"A guy came up to us and said if we were really careful we could get past on the grass and we managed to do that. It was pretty freaky. Our car is quite low and there wasn't a lot of room. We only just managed it."
Ngongotaha Volunteer Fire Brigade Station Officer Paul Osborne said two crews and the Rotorua operational support vehicle attended.
"It had the potential to have been a lot worse if someone had been driving past at the time," he said. "If it had been around home time it would have been a different story."
