Contractor Rigg Zschokke was about to start bringing in the pre-fabricated structures which had been constructed in Masterton.
Structures like the prenail frames, would go up at the site soon, said Bryce Jolliffe, Rigg Zschokke site foreman.
Mr Pollard said the design of the building was modern.
"It's a very contemporary grocery store for the local community."
The $2.5 million project is expected to take six months to complete.
The existing post office and Lotto shop will be a part of the new supermarket and there will also be a new bottle store attached to it with a separate entrance.
The outdoor area of the complex will have a glass wall to act as a windshield along with a new carpark.
