Watt said he was happy to lead the initiative to support men's health because the funds raised would support mental health and suicide prevention, prostate cancer and testicular cancer.
Movember was conceived by Australian friends Travis Garone and Luke Slattery over a quiet beer in 2003 and they went on to challenge a bunch of mates to grow moustaches and contribute $10 each to support prostate cancer research and treatment.
The concept was formalised the following year with company registration and the launch of a website that has spread the message around the world. The campaign was launched in New Zealand in partnership with The Prostate Cancer Foundation of NZ in 2006.
As more and more moustaches are grown each year, the range of Movember's support for men's health has also grown and while the charity continues to fund research and treatment for prostate and testicular cancer, it also provides funding for a range of wellbeing, mental health and suicide prevention initiatives.
The campaign has also introduced new ways to participate and there are now options to Grow a Mo, Move for Movember by taking part in a walk or run, Host a Mo-ment by rallying a crew for a fun challenge or Mo Your Own Way with a wild card idea of your own.
