There has been speculation for weeks that Mr Obama was coming to New Zealand, and it has been announced he will speak at a New Zealand-United States Council event on 22 March.
"President Obama's presidency had an extraordinary impact on the world and during his service, New Zealand's deep friendship with the United States was strengthened politically, culturally, in trade and investment, innovation and security," council chairman Leon Grice said.
The New Zealand-United States Council is a not-for-profit dedicated to supporting and strengthening the two countries' bilateral relationship.
