The council was planting new street trees across Tairawhiti and would be looking to replant in Grey Street as soon as possible, she said.
Nearby businesses and residents were notified of the tree removal work by letter last week. The work will be done in three stages.
Contractors needed to close areas of the road and traffic controllers would be on site to guide vehicles and pedestrians, Ms Frey said.
“However, we ask the community to please try to avoid the area if possible.”
Woodchippers on site could create noise disturbance.
The council is looking to distribute the wood chips to local schools and charities, and encourages anyone interested in the chips to contact Roberts Tree Surgeons on 06 868-6463.
