Joseph Parker's handlers aren't backing down from speculation in the United Kingdom the New Zealand heavyweight boxer could be matched against former world champion David Haye.

Haye's comeback in Britain continues to gather momentum and, after winning his last two fights, it's a question of who's next for the 35-year-old who held the WBA belt for two years before losing to Wladimir Klitschko in 2011.

Haye is slated to fight American veteran Shannon Briggs but commentators feel that will do his credentials little good in a British heavyweight market bulging with talent.

Sky Sports in the UK suggested a clash with Parker would be a better test labelling it "an explosive fight with plenty at stake".

The worry for Parker is the threat that would place on his mandatory challenger's position to Anthony Joshua's IBF belt.

But Parker's promoter Dean Lonergan of Duco Events made it clear that Haye would be considered if Parker progresses past his next fight against Australian veteran Solomon Haumono in Christchurch  on July 21.

"If the money and conditions were right, Joseph and his team would consider any major fight in the UK, including David Haye," Lonergan said.

Joshua's promoter Eddie Hearn is eager to get Parker on a fight in Britain ahead of the mandatory challenge ( that time frame opens on November 19 but could be stalled by a unification bout that takes precedence) to boost his profile there.

A clash with Haye would be a major attraction on the undercard to a Joshua promotion.

The big question for the Parker camp would be whether it would be worth the risk involved to the looming title bid?

Haye has been seen as an overblown cruiserweight. But he has speed and power and crafty ring knowledge – a testing combination against the 24-year-old Parker.

His comeback after three and as half years of inactivity has drawn mixed responses.

The benefits might lie more in the Haye corner than Parker's, especially if Haye's latest win can take him inside the IBF's top five rankings, meaning any clash with Parker would have automatic mandatory rights attached to it.

A victory for Parker though would certainly push up his bargaining power for his inevitable fight with Joshua where the purse could be enormous.
