Recent monitoring has confirmed renewed movement within the main landslide area on Mauao above the Mount Maunganui Beachside Holiday Park. Since last weekend, six additional slip events have been recorded, including a significant movement on Friday evening.
Geotechnical specialists have identified fresh cracking and evidence of groundwater emerging from the slope, both of which indicate the affected area remains highly susceptible to further movement. As a result, the landslide is considered active and ongoing.
Current safety controls, including the closure of Adams Avenue, will remain in place for the foreseeable future while experts continue to assess the site and monitor conditions. Residents and visitors are asked to respect all closures, barriers and signage and avoid entering restricted areas.
Recovery Manager Charlie Rahiri said the latest activity demonstrates why a cautious, evidence-based approach remains essential in managing recovery efforts on Mauao.
"Our monitoring systems are designed to detect changes in slope behaviour and provide early warning when conditions change. The recent movement triggered established response procedures, allowing us to act quickly and put appropriate safety measures in place," says Charlie.
"While this movement is a reminder that Mauao remains an active environment, it does not change our commitment to restoring access where it is safe to do so. We've made substantial progress over recent months and will continue to be guided by specialist advice as recovery work progresses," says Charlie.
Repair works on Te Ara Tūtanga (base track) are continuing as planned. Other known landslide sites on Mauao continue to be monitored and are not currently showing signs of significant change. Initial assessments have also not identified damage to the Motukauri (summit 4WD) track, although inspections will continue.
"Public safety remains our priority. We will continue to work closely with our geotechnical advisers and mana whenua partners to ensure decisions are informed by the latest information and reflect the long-term wellbeing of the maunga and those who use it," says Charlie.
