Chisora lacked variety in his points defeat to Oleksandr Usyk last time out, while Parker has enjoyed four straight wins since back-to-back defeats to Anthony Joshua and Dillian Whyte.
The New Zealander was pushed close last time out by Junior Fa, and any hopes of regaining a version of the world heavyweight championship is dependent on a clear victory over his British rival here.
Parker is ranked inside the top eight with the WBO, WBA and IBF, while Chisora is 15th in the WBC’s latest rankings.
It promises to be an intriguing undercard with Katie Taylor defending her world titles against Natasha Jonas, while Chris Eubank Jr is back in action, light heavyweight world champion Dmitry Bivol features and Campbell Hatton’s journey continues.

Chisora on Parker
“We’ve been here before, in 2019 I flew to Vegas to film the ‘Face To Face’ with Parker, I called Haye as soon as I left and told him, ‘This guy isn’t going to get in the ring with me’, I could see the fear in his eyes,” said Chisora.
“Now, second time around I hope he fights, I’m looking forward to the fight, I cannot wait to get back in the ring! I love fighting, it is what I love the most. Good luck to Joseph Parker and his new team, we shall see you for WAR on May 1st!”
Parker on Chisora
“I’m excited to start this new chapter in my career with a new coach and some fresh ideas,” said Parker. “I’ve settled in and Andy and I are bonding well. Chisora and I have unfinished business and inside the ring one of us will get the job done.
“I am well aware that a win on British soil and on world-wide television will put me in pole position whereas a loss will be catastrophic. I am more than up for the challenge. Bring it on Del Boy.”
