Joseph Parker is one fight away from a shot at the IBF title after details for his elimination bout against Carlos Takam were finally agreed on.

A contract for Joseph Parker's IBF heavyweight elimination bout against Carlos Takam has been signed.

Parker's promoters Duco Events will reveal details at a media conference in Auckland on Wednesday.

The fight will be held in Auckland on May 21.

Duco have revealed the fight will offer the biggest boxing purse in New Zealand history – surpassing the $1m shared between David Tua and Shane Cameron in 2009.

Duco Events confirmed that the lengthy negotiation process with Takam's management had finally been completed.

The agreed contract between the two fighters' camps avoids a purse bid situation being implemented by the IBF.

The fight will see the winner go on to be the mandatory challenger for the winner of the IBF title fight between champion Charles Martin and Anthony Joshua.

Duco Events now face the massive task of making the promotion financially viable.

Auckland's corporate market will be heavily targeted and a lot of the revenue will be recouped in pay-per-view sales where the Tua-Cameron fight still holds the New Zealand record of 85,000.

Takam's exotic background – he is Cameroon-born, France-based and Italian-managed – opens doors in French-speaking regions.

Parker has a growing profile in the United States while there has been plenty of working into pushing his growing claims into Britain where the heavyweight scene is blossoming.

This will be the biggest test of Parker's unbeaten professional career that now has 18 wins, including 16 knockouts.

The 35-year-old Takam is ranked No 5 by the IBF, one place ahead of Parker.

Takam has 35 wins – 26 via knockouts – a draw and two losses in his record.

He is ranked inside the top 15 by three of the four major organisations.
