The boxes will be filled with harakeke/flax as part of a partnership between Passionart NZ, the Highbury Weavers Group, and Palmerston North City Council.
"This project will not only provide a point of difference for Broadway, but also provide resources for the Highbury Weavers Group to share their traditional weaving techniques," says Policy Planner Keegan Aplin-Thane.
Nineteen trees were felled in the Avenue in February and a selection panel made up of design experts, iwi carvers and a representative from Broadway property owners was convened to consider what to do with the space.
"This Placemaking Initiative contributes to its overall mission of enabling locals to experiment with public space to build a stronger sense of identity", says Mr Aplin-Thane.
The installation and planting of the flax will coincide with Broadway's Pulse Urban Festival on November 29.
Palmerston North Mayor Grant Smith is pleased the project is underway.
"We are a city of makers, doers, and thinkers, so Council should be responding to this culture by enabling people to try new things and stand out from the rest."
Mayor Smith says the project is designed to be temporary.
"The benefit of these planters is that they can be repurposed at a later time if Broadway evolves into something new."
