Associate Education Minister John Banks says he believes the Genesis account of the start of life on Earth.
According to the Bible, God made the world in six days, with Adam and Eve being his last act of creation.
John Banks told Radio Rhema that he has no doubts the first chapters of Genesis are true.
"That's what I believe, but I'm not going to impose my beliefs on other people, especially in this post-Christian society that we live in, especially in these lamentable times.''
"There are reactionaries out there, humanists in particular, that overrun the bureaucracies in Wellington and state education.''
