Kiwi businessman Harry Mowbray is on the defence today, after claiming swing voters who shape the balance of power are 'women driven by emotion' who tend to pull politics to the left.

Mowbray was one of the bigger names who encouraged voters to to give their electorate vote to National and their party vote to Act or New Zealand First.

He explained that he's read up on the demographics of swing voters - and they're primarily women.

"And they vote on emotional things, or having a few extra dollars in their budget for the week. And so that is apparently what the statistics say, and so that's where the focus is."
