A Newshub investigation has revealed the extent to which the global far-right movement has infiltrated New Zealand.

Newshub's National Correspondent Patrick Gower has looked into links between the alleged Christchurch shooter Brenton Tarrant and the far-right movement in Europe.

He found that part of a donation made by Tarrant to European far-right leader Martin Sellner was then given by Sellner to Victim Support for the Christchurch mosque attack victims.

Victim Support will offer the money back to Sellner or give it to an anti-racism group.

Gower joined The AM Show on Tuesday to discuss the case, and how the National Party has opposed the United Nations Migration Compact, something Sellner has also publicly rallied against.

Watch the interview above.
