Delegates at the USNZ Pacific Partnership Forum meeting in Washington DC have expressed sorrow at the loss of life in the Oklahoma tornado.
NZUS executive director Stephen Jacobi said delegates made note of the Canterbury earthquake, which had disrupted the last forum meeting.
"Now the people of Oklahoma are facing devastation and loss of extraordinary proportions.
"Our hearts go out to the people of Oklahoma."
Mr Jacobi said the NZUS Council would make a donation to the recovery effort and, reflecting the support received from American friends at the time of the Canterbury earthquake, would seek further contributions from New Zealand Forum delegates.
