The four kainga and four ngoi pou unveiled were used to mark the rising and setting points of the stars, sun and moon to navigate waka on the open ocean.
Mr Smith was one of a team of carvers, including head carvers Nathan Foote and Phil Belcher, who created the pou.
He said that he and Paora Puketapu, Te Kaha Hawaikirangi, Deon Wong and Rangitane Taurima were novices when they started the work one and a half years ago, the ornate carvings created from old power poles.
The first of the carvings were installed in December last year, timed to pinpoint the summer solstice when the sunset and sunrise were visible on the horizon from the star compass.
"For everyone this has been awesome, being under Nathan and Phil's guidance we have been able to put up some things that the guys are proud of."
For students of traditional navigation, the Celestial Star Compass had provided a valuable educational tool, and also a way for all people to get in touch with the seasons and understand more about their relationship to the sun, moon and stars.
The remaining eight pou will be placed in time for this year's summer solstice in December, as well as a waharoa (gateway).
Over winter, volunteers have been planting the surrounding area, co-ordinated by the Hawke's Bay Regional Council, in addition to the wetlands, new pathways, story boards and a new carpark that had been built.
