Chart-topping New Zealand pop and rock stars Julia Deans and Anika Moa embark on their ''New Hearts Tourette'' together, the first chapter in a tour to be played over 12 months.

They will play new songs from their forthcoming solo albums and join forces for some crowd-pleasing old favourites.

''Anika will probably tell some really funny stories and I'll just stick to my repertoire of dad-jokes,'' Deans said.

Her second solo album is called We Light Fire.

Moa said audiences could expect ''heaps of new tunes and lots of silly nonsense from me.

''Good stories and a well-travelled repertoire. We can't wait to hit the South; it's been a long time coming.''

• The artists play at the River House, Wanaka, on May 4.

• Moa will reunite with Boh Runga and Hollie Smith to return to the Wakatipu to perform as a trio supporting the family counselling service in Queenstown. They play at the black-tie fundraiser at Stoneridge Estate, Lake Hayes, on June 7.
