Late Show host Stephen Colbert shares the screen with Sir Peter Jackson

Stephen Colbert has shared the screen with Sir Peter Jackson in his latest attempt to become "The Newest Zealander".

The fourth instalment of the American's tour of Aotearoa included a remake of Sir Peter's famous Lord of the Rings series.

The host of The Late Show with Stephen Colbert returned to the heart of Middle Earth, having cameoed in The Desolation of Smaug, and suggested a new trilogy for Sir Peter to direct.

"What if we spun off my character Laketown Spy into his own series of trilogies?" Colbert asked.

It was a short "no" from Sir Peter.

Earlier in the week, Colbert learnt about rugby from All Black legends Piri Weepu and DJ Forbes. He was taught about scrums, and even attempted tackling.

He found his training so intense he had to be carried from the field.

But he concluded that he's now a threat on the field.

"You have no killer animals down here, nothing can kill you on this island. You let a bear in, a 'Col-bear', watch out," he said.

Colbert is passing his love of Aotearoa on to his audience of 4 million viewers, and Tourism New Zealand hopes to score some points in the hearts of Americans.
