Christchurch NZ is keeping the door open to SailGP, hoping racing can happen again in Lyttelton next year.

Last weekend's event has been marred by debate on measures to protect dolphins, with SailGP CEO Russell Coutts casting doubt on future hosting plans.

A dolphin sighting meant Saturday's race was cancelled.

Christchurch NZ's Loren Aberhart says a contract's been signed, but they are still open to discussions.

"But I think from our perspective, when you look at the way it went yesterday- it was incredible. And Pete Burling texted me saying it was the best SailGP he's ever done."
