A further $2 million has been made available to address weather-tightness issues at Mahurangi College.
Associate Education Minister Nikki Kaye visited the school on April 2 to inspect the work that is currently underway.
The initial cost to repair leaky building issues at the college was $4.5 million.
During her visit, Ms Kaye said this had been increased to $6.3 million.
She said the current project included repairs to the college’s water-damaged junior block and library, and rebuilding the arts block.
“Last year the science block was repaired and strengthened to meet the current building code, and repairs to the student centre are also being looked at.
“This is not just about fixing leaky buildings, it’s also about providing students with an environment that excites and inspires them to learn and achieve.”
Ms Kaye said the current work at Mahurangi College is expected to be completed by the end of this year.
