Taupō Airport investigates major runway rebuild

Wednesday, 24 June 2026

Taupō Airport’s main runway was scheduled for $800,000 worth of repairs until engineers found further deterioration that could cost a whole lot more to fix.

Taupō Airport has cancelled a planned $800,000 runway repair project after engineers found the main runway had deteriorated more than first thought, raising the prospect of a much larger repair bill.

A report to the Taupō Airport Authority (TAA) committee states an extensive assessment by aviation consultants AECOM found the airport's main sealed runway no longer suited the repair work planned for this financial year.

The repairs had been proposed to address cracking and general surface deterioration on the main runway.

Taupō Airport’s main runway has been deteriorating at a faster rate than expected.

However, airport management says the latest inspection found a 'marked deterioration' since AECOM's previous survey in 2022.

In its own report, AECOM concluded that carrying out the planned work now would neither improve the runway's condition or meaningfully extend its operational life.

'To surface treat at this stage would neither achieve any betterment nor prolong the life expectancy of the runway,' the report states.

Instead of proceeding with the project, the TAA will undertake further work to determine whether the deterioration is confined to the surface or is being caused by more serious structural problems beneath the runway.

AECOM has recommended a programme of additional testing, including taking core samples from selected locations along the runway and carrying out deflectometer (a device used to evaluate the physical stiffness, load-bearing capacity, and structural integrity of soils, pavements, and materials) testing across its full length.

Core sampling is expected to take place during July and August, while the specialised deflectometer testing is tentatively scheduled for August or September when the contractor undertaking the work moves to the North Island.

The testing is aimed at answering the question as to why the surface condition has declined - is it purely a surface problem or a “more serious underlying issue with the pumice base?”

The report states that if the problem is more serious, it could have “major financial implications”.

The planned surface treatment, estimated to cost $800,000, was to be funded equally by the Ministry of Transport and Taupō District Council.

That project has now been cancelled, with airport management recommending the funding instead be shifted into the 2026/27 financial year while further investigations are completed.

'It may be the case that more extensive works will be necessary, especially if the pumice base is failing,' the TAA says.

No estimate has yet been provided for what those extensive works could cost.

The report does not identify any immediate operational or safety concerns, and there is no indication that flights will be affected while investigations continue.

The TAA says it will report back to the committee once the additional testing has been completed and engineers have a clearer understanding of the cause of the runway's deterioration.
