This is the adorable moment the baby son of Kiwis rugby league star Tohu Harris giggles as his dad teaches him the haka.

Harris, who plays for the Melbourne Storm and is on tour in the UK with New Zealand's Four Nations team, uploaded the video of his 5-month-old son Harlan dressed in a stripey navy and white onesie to his Instagram account.

In the video, the 24-year-old father holds his son's hands gently and whispers the words of the traditional Maori war cry as Harlan playfully moves along.

At one point in the performance Harlan opens his mouth and appears to roar as his dad takes him through the motions of the historic chant.

The video was quickly picked up by the NRL official Facebook account and shared to its 1.3 million followers, where thousands of people commented on it.

"Thank you for this one, reminds me of my dad with the boys when they were babies," wrote Larn.

"That is just so precious and he will probably know it by the the time he can walk," added another.

Harris, who lives in Melbourne with his wife Nat, was born in Waipatu on the fringe of Hastings.

He moved to Victoria when he was 17 and signed with Storm in 2013, the same year he debuted as an international star with the Kiwis.
