The Olive Press opened its new, larger, purpose-built premises in Greytown on Sunday with Primary Industries Minister Nathan Guy doing the honours.
Bill Hey, operations manager, said the olive-pressing business had been operating in Masterton since 2000 but outgrew the premises by 2008.
He said a plan to move into a bigger building had been in the works for three years and the foundations went down in December.
"We have been flat out ever since, it's been an amazing, quick build. It's five times larger than where we were."
Mr Hey said it was a sensible place to be - closer to growers and tourists passing through the "Golden Triangle" of Martinborough, Greytown and Featherston.
