The slip made headlines back in March when it formed a large lake, containing an estimated 400,000 cubic metres of water, silt and trees.
A slow release of the dam alleviated risk three months ago, but heavy rain over the past week was again creating issues.
Te Hau-Ward said she hadn’t received a clear answer from Gisborne District Council on who was monitoring the slip, and at what frequency.
“We’ve been posing the question the past two weeks, and don’t have a definitive answer.
“If the slip dams the Mangahauini River again, how will locals know?”
Civil Defence group controller Ben Green said the Mangahauini slip had been assessed with satellite imagery and drone footage obtained by an East Coast farmer.
Tokomaru Bay would be alerted immediately to any imminent threat, he said.
“The Mangahauini slip is being monitored by Council and GNS experts with the information provided to Council.
“We are also in contact with Te Runanganui o Ngāti Porou, who’ve been part of our Incident Management Team meetings that were held up to six times a day during the State of Emergency.”
Up the road in Ruatoria, Radio Ngāti Porou’s Paora Brooking said the rain had been consistent over the weekend, creating phone and internet issues.
He felt for people who were doing it tough outside of the main township, and said the weather events continued to impact people’s mental health.
“We’re going to need more than a few days to dry this place out. You walk on the lawns and you’re sinking.
“Everybody’s feeling it, they’re over it.”
According to the council, 565mm of rain was recorded at Raparapaririki, inland from Ruatoria.
Brooking said some had self-evacuated over the weekend, and farmers were continuing to feel the impact.
“Hopefully the resilience of our people is enough to get us through this, and hopefully we’ll see brighter days.”
A state of emergency in Tairāwhiti was lifted on Sunday, three days after Mayor Rehette Stoltz put it in place.
