Video: Stan Walker's heartfelt new single dedicated to his 'superwoman' mum following cancer battle

After baring all in a recent documentary revealing his ongoing cancer battle, Stan Walker is set to release a heartfelt new single dedicated to his mum and her tireless support.

A music video for the new song, aptly titled Thank You, will be released on Wednesday.

The vision Walker has paired with the tune revolves around family, and contains many shots of his mum and relatives.

"After all we've been through, you've never run out of love," Walker sings.

"There's no words to say but 'I love you', so I'm a say thank you - just know it will never, ever be enough."

Last year, Walker discovered he has a rare cancer-causing gene mutation responsible for the death of 25 members of his family.

The genetic mutation which runs in Walker's family is expected to cause stomach cancer in 70 per cent of people by the age of 40.

The recent documentary Stan, follows the Kiwi singer through the process of having his stomach removed after the first stages of cancer were discovered in the organ.
