Air New Zealand will operate 52 extra one-way flights to help get Ed Sheeran fans to and from Auckland and Dunedin next March.

This will mean an extra 7000 seats for fans of the Grammy Award winner who is now playing six shows in this country.

The airline will operate 35 additional one-way services between Dunedin and Auckland, Christchurch and Wellington as well as 17 extra one-way flights between Auckland and Christchurch and Wellington, using a mix of the airline's A320 jets and ATR aircraft, in the days leading up to and after the singer's two Dunedin shows and three Auckland performances.

Air New Zealand regional general manager direct and market development Jeremy O'Brien said the extra flights would provide 7100 extra seats for Ed Sheeran fans travelling to his concerts from throughout the country.

''There's been huge demand for tickets so we look forward to helping get fans to Auckland and Dunedin to see him perform."

The extra flights go on sale this afternoon.

Sheeran will perform at Auckland's Mt Smart Stadium on March 24, 25 and 26, and at Dunedin's Forsyth Barr Stadium on March 29, 31 and April 1.
