Shortland Street stars will join thousands of New Zealanders taking part in Live Below the Line for charity.
For five days next month, Ria Vandervis, who plays Dr Harper Whitely, Amy Usherwood (nurse Emma Franklin), Sam Bunkall (surgeon Boyd Rolleston) and Kerry-Lee Dewing (nurse Kylie Brown) will live on $2.25 a day for Oxfam.
The annual event will run from September 23 to 27, and challenges participants to feed and hydrate themselves on $2.25 a day, the New Zealand equivalent of the extreme poverty line.
The initiative, launched by education and campaigning organisation Global Poverty Project, aims to raise awareness of the 1.2 billion people who are forced to live on the line every day. Oxfam is one of eight charities taking part.
Usherwood jumped at the chance to be involved but has become increasingly nervous about participating.
