Former United States president Barack Obama will visit Australia next month as part of a trip that will also see him speak in New Zealand.

The New Zealand United States Council announced on Sunday it would host Mr Obama at speaking events in Auckland and Sydney on March 22 and March 23 respectively.

'President Obama's presidency had an extraordinary impact on the world and during his service both Australia's and New Zealand's deep relationships with the United States were strengthened politically, culturally, in trade and investment, innovation and security,' council chairman Leon Grice said in a statement.
