Mr Masfen told the Business Herald that shareholders had many questions about GPG's interest in the company, but had expressed "no strong opinions either way and have no reason to feel insecure."
He said he had no idea if GPG was likely to increase its shareholding, saying only that GPG director Tony Gibbs was "thrilled to be a shareholder and regarded the company as exciting."
Montana was a strategic purchase that had attracted plenty of interest, Mr Masfen said, although he declined to confirm whether Foster's or Lion Nathan - the two companies most strongly rumoured to be eyeing up Montana - were among those interested.
Once again he denied he would be selling down his 20 per cent holding in Montana.
