Monitoring alarms on Mauao have activated again as experts continue assessing the unstable landslide above the Mount Maunganui Beachside Holiday Park.

The alarms, which are part of the landslide monitoring system, were triggered on Monday, Tauranga City Council said in a media release.

The latest alert comes a day after several slips reactivated the landslide that killed six people in January, prompting fresh concerns about the stability of Mauao.

The council said the alarms could activate for a range of reasons, including movement or changes detected within established thresholds, and did not necessarily indicate an immediate risk to public safety.

The council said it responds to every monitoring alarm through a risk‑based assessment, checking conditions to decide whether any action is required.

Council staff and technical specialists are now reviewing the alert data and carrying out inspections where needed, and keeping the public informed if further updates are required.

Mount Maunganui MP Tom Rutherford said fresh slips of Mauao over the weekend have been "gutting".

Recovery manager Charlie Rahiri described the movement over the weekend as a “major regression” and said about 8000 cubic metres of earth had shifted. The January landslide involved an estimated 12,000 cubic metres.

The council warned the latest slips reinforced concerns the mountainside remained “highly unstable” and said further geotechnical assessments were underway to better understand the ongoing movement.

Bay of Plenty MP Tom Rutherford said the reactivation was “really, really sad” and “really gutting” for the Mount Maunganui community, but urged people to continue supporting local businesses.

“If I could send a clear message to anybody listening today, I want to tell them Mount Maunganui itself, the mountain may be closed, but the Mount Maunganui area and main street and shops are well and truly open.”

Adams Ave, between Pilot Bay and the Maunganui Rd roundabout, remains closed to vehicles as a precaution while the slope is monitored and experts continue their assessments.
