The Boars first requested the move back in September last year, but have spent significant time waiting to find out if they would be given approval.

Following a merge of Country Rugby League (CRL) into NSWRL, the board said there would be no boundary changes for two years while it reviewed the the boundaries and competition structures across the state, which is expected to be complete by the middle of the year.

However, NSWRL ruled at a board meeting last Friday that it will permit the Boars move to Group 4 for the 2020 season only because of special circumstances, pending further reviews.

"Notwithstanding this, after the Board considered the particular request from the Moree Boars, they were satisfied that there are special circumstances which require the request to be granted in this instance," NRWRL chief executive David Trodden said.

"It is important to understand that the approval for the transfer from Group 19 to Group 4 is strictly for the 2020 season only and subject to the findings of the review of boundaries and competition structures."

Moree Boars president Todd Mitchell said it's been a long road to get to this point but is pleased with the result.

"We are happy about being back in Group 4 and we are looking forward to the season ahead," Mitchell said.

"We made contact with Group 4 right back in April last year, expressing our interest in returning to Group 4.

"Group 19 have been very accommodating over the past six years and all the clubs made us welcome when we changed in 2014 to Group 19."
