Claims truth is the first casualty of the election season

Labour leader Chris Hipkins has apologised today - after his party released social media ads with misleading information.

The videos alleged a National Government would reverse the Government's first-year fees-free policy for tertiary education.

But past-Prime Minister Jacinda Ardern's former chief of staff says this is going on right across every party.

Mike Munro says he's just seen data about Tweets posted by National's Simeon Brown and Chris Bishop.

He says there's dozens and dozens of examples of false and misleading information coming out from the pair - but no-one's paying attention.
