"Tradition's important, but I think promoting men's health is just as important. My father has taught me the importance of getting regular health checks, and that it's okay to seek help even for mental issues ... this is what Movember's all about."
Commander Peebles was shaved with a cut-throat razor at the Devonport Naval Base by professional groomer Hitomi Shiraishi from the Grooming Lounge.
Leading Marine Technician Jeremy Jeffs, 30, said sailors had been "real excited" about being part of Movember with the rule change and all but four of the 28 men on his ship, HMNZS Rotoiti, had signed up.
Last year, more than 15,000 men and women registered to raise over $1.57 million for men's health issues, including prostate and testicular cancer and mental health.
Funds raised through Movember go to the Mental Health Foundation and the Cancer Society, funding programmes to improve men's health. Organisers are setting a target of 20,000 this year for the month-long event, but are hoping for at least 18,000 registrations.
Movember manager Rob Dunne said about 7000 people had already registered, and urged more to "shave off any residual facial hair and start fundraising".
The men's suicide rate is nearly three times that of women and they die, on average, four years younger.
About one male adult passes away prematurely every three hours from a preventable illness. Mr Dunne said Movember was aimed at creating conversation and a strong community of understanding around men's health.
The movement began in 2003 when Aussie blokes grew moustaches during November for fun, but is now a global foundation with representation in more than 21 countries.
Yesterday sports presenter Martin Tasker, the voice of the America's Cup, shaved his mo for the first time in 41 years live on television, and other celebrities are following suit.
