The $1 million road link in Papamoa was built ahead of schedule after the Maori Land Court gave its consent in October for Mangatawa Papamoa Blocks Incorporated to donate a 400-metre strip of land behind Pacific Coast Village for the link.
Mr Haua said it was a special day for the corporation.
"It means housing and education, it will be a well used road."
Paula Loader attended the opening with her children Rachel, 10 and Sophie, 7.
"We'll use this all the time," Ms Loader said.
She thought it would probably make travel easier for them, depending on the traffic.
Mr Wilkinson said the link would free up congestion along Maranui St and provide another route to the Pacific Coast Village.
He said the village had grown rapidly in the last six months, and the road would be beneficial to that growth.
"It allows us to accelerate in many ways."
"This is a great place to live," he said.
