Approximately 120 hours of work went into carving the artworks, which are located on the southwestern side of the roundabout and stand at approximately 8 metres tall. A limestone path and bollards have also been installed.
Waka Kotahi Central North Island's regional manager for infrastructure delivery, Rob Partridge, said it was a special way to close out the project.
"Coming together today is also a celebration of Waka Kotahi's partnership with mana whenua and our commitment to linking our works with the history, the stories and people of the Hawke's Bay region.
"It's been a real team effort, and I'd like to thank local iwi, our contractors and Waka Kotahi staff for making it happen."
New Napier councillor Chad Tareha, a descendant of Chief Tareha Te Moananui, led the blessing ceremony.
"It has been a long journey, and it's exciting to see the pou at their final place. So much hard work went into this project, and I would like to acknowledge everyone who was involved. It's such a special day."
