No dieback on Glenfield kauri

Young kauri trees planted in Glenfield and sporting a shade of brown are not suffering from dieback disease, Auckland Transport says.

The median strip at the Glenfield/Wairau roads intersection is home to juvenile kauri planted earlier this year.

Kaipatiki Local Board member John Gillon says he reported the issue to Auckland Transport as the trees "are looking sick".

Planting kauri at the intersection was a condition of the Glenfield Rd upgrade, signed off by the former North Shore City Council.

The North Shore Times asked Auckland Transport if the trees were suffering from kauri dieback disease. A spokesman says a landscape contractor had a look at the trees.

"He says the browning is a natural process. He has been back in the past few days and is happy with the state of the trees. There is no suggestion of any disease issues."


Mr Gillon says he is "not sure I believe that as the kauri planted closer to Glenfield shops aren't brown".

Mr Gillon says he was told an "irrigation problem" was being looked into.

"I just hope that it is a watering issue due to the hot weather and not kauri dieback disease, as brown leaves is one symptom of that."

Auckland Transport says leaf and debris drop are natural processes of all trees.

"The kauri self-prunes in the juvenile ‘ricker' stage, making it practically maintenance-free."

The kauri are planted in a sealed soil vault. This restricts the potential size the kauri could grow to and it is believed they will remain in their juvenile stage, the spokesman says.

Concerns were raised in April that the kauri, which can grow up to 50 metres high, would eventually grow so big they would cause road issues.
