The function at TenTwentyFour restaurant was also a chance for departing editor Antony Phillips to say farewell.
Mr Phillips said the new-look morning edition would be improved with new columnists, features and a smarter but familiar appearance.
"We are the newspaper of the Hawke's Bay community and any opportunity to be read for longer is of value to all," he said.
Mr Phillips, who is moving to a new role in Australia after two years as editor, introduced his successor, Andrew Austin. Mr Austin was chief reporter for the New Zealand Herald: "I am inheriting APN's best performing regional paper and there is not too much to change, just a bit of tweaking further down the track."
