The winery has been significant enough throughout New Zealand's wine history that the Montana name is still used on domestic labelling due to its strong brand recognition.

Two of Ivan's son's, Mate and Frank, had become involved, and they set up the company Montana Wines in 1961.

Many of the grapes for Montana's sparkling wines are pressed here, but secondary fermentation is carried out at the Tamaki Winery.

It was a more commercial scale facility than Church Road and contributed to Longridge, Corbans, Verde, Huntaway and Robard & Butler brands.

The Corbans brand was sold to Lion in 2010, and in 2012 the winery was closed with most of its production integrated into the nearby Church Road facility.

In 2010, Pernod Ricard sold the winery and some associated brands to the Lion Indevin partnership.

This also means that all sparkling wines undergo secondary fermentation (in the bottle) in Auckland.

It produces mainly Merlot-Cabernet blends, Syrah, Chardonnay, Pinot Gris, and Sauvignon Blanc in several tiers.
