Work is progressing on efforts to reopen Adams Ave and the Pilot Bay boat ramp following the reactivation of the landslide behind the Mount Maunganui Beachside Holiday Park.

Adams Ave was closed to vehicles on July 24 as a safety precaution after the landslide reactivated, Tauranga City Council said in a media release.

Since then, work has been underway to strengthen protection along the holiday park’s harbourside boundary and improve the road’s resilience to future landslide activity.

The council said about 900 tonnes of rock will be used to create a protective barrier beside shipping containers already installed at the site. Rock-filled bags will be placed on the holiday park side of the containers to provide additional support in the event of future slips.

Adams Ave and the Pilot Bay boat ramp are expected to reopen before the end of August, subject to favourable weather and site conditions.

The boat ramp’s reopening will also depend on the completion of geotechnical inspections.

The council said any permanent repair work for the landslide area must take into account the long-term future of the holiday park site, as well as findings from an ongoing technical assessment.

It also said the improvements would significantly increase the resilience of Adams Ave and were expected to allow the road to remain open during Trigger Action Response Plan (TARP) Level 3 conditions, but the boat ramp may still need to close temporarily during periods of elevated landslide risk.

As part of ongoing safety measures, landslide warning alarms will be tested every Monday and Thursday morning while construction work continues. Once the project is completed, testing will return to its usual Monday-only schedule.
