On November 10, 1915, Governor-General Lord Liverpool arranged a meeting to co-ordinate the activities of groups of people raising money and sending medical supplies to New Zealand troops at war overseas.
From this meeting the New Zealand Branch of the British Red Cross was born.
Almost a hundred years later, Red Cross is still going strong in Hawke's Bay and throughout the country. In fact the first woman national president, Helen Lowry, was from Hawke's Bay.
To celebrate, Professor Margaret Tennant has written a book, A History of the Red Cross in New Zealand 1915-2015.
She will speak at a book launch at the Hastings RSA today, from 2.30pm.
