A 6m pōhutukawa planted in Mt Albert recently may have been poisoned and thousands of dollars of ratepayer money could be down the drain should the dying tree need replacing.
The pōhutukawa was planted in January on New North Rd as part of the Mt Albert Town Centre upgrade.
Auckland Transport was investigating why the tree's health had deteriorated and told the Herald a replacement would cost about $15,000.
"We are getting an arborist to check the health of the tree," Auckland Transport spokesman James Ireland said.
