Late Show host Stephen Colbert learns how to be an All Black with Piri Weepu and DJ Forbes

American chat show host Stephen Colbert has tried his hand at rugby with some help from familiar local faces.

The segment, aired on Thursday (NZ time), is part of The Late Show with Stephen Colbert's spotlight on Aotearoa this week as he tries to become 'The Newest Zealander'.

The star found it so intense he had to be carried from the field.

Former All Black Piri Weepu, former All Black Sevens captain DJ Forbes and Sky Sport presenter Laura McGoldrick all pitched in to help Colbert learn about the national sport.

He asked what the name 'All Blacks' meant, McGoldrick telling him it refers to the entirely black uniform.

"We have a team in the United States called the 'All Whites', and it's the Republican Party," he quipped.

Colbert said he played American football during high school for one day and he "threw up for most of it".

First in his rugby training was learning "how to tackle things", and DJ Forbes was on the receiving end. Colbert hyped himself up and taunted Forbes, claiming he was going to give him a "badge in pain".

"You wanna call your mummy before we do this?" he said, before Forbes easily sidestepped him.

Colbert continued his training with lineouts and a scrum, and he even nailed a conversion kick from in front of the goal posts.

On Tuesday's segment, Colbert was picked up from the airport by Prime Minister Jacinda Ardern and had a barbecue at her house with pop singer Lorde.

He met with Flight of the Conchords singer Bret McKenzie and actress Lucy Lawless in Wellington on Wednesday where he learnt how to become "a real New Zealander", donning jandals and trying Marmite.

Colbert's trip to New Zealand came after Ardern invited him during an appearance on his CBS show.

His tour cost taxpayers $100,000, which contributed to accommodation, domestic travel, activities and attractions. Tourism New Zealand estimates $5 million in advertising value from his trip.
