Mr Bishop said the site was launched after "talking with its [Phillip Morris] consumers... who wanted a place to learn about the regulatory issues the New Zealand government are looking at."
They want a chance to voice their opinions, he said.
But anti-smoking group Action on Smoking and Health say the website is a last-ditch attempt from the tobacco industry.
"When your company gets to the point where it can no longer engage constructively with policy makers and starts to attack them through a website, it shows you are dying," said director Ben Youdan.
Mr Youdan told the Herald the site was a sign Phillip Morris were "very, very afraid" about an increase in anti-tobacco measures.
The tobacco giant are also planning to issue retailers with postcards pointing cigarette-buyers to the website.
Mr Bishop said the postcard scheme was completely voluntary, and no shops would be pressured into handing out the cards.
