The Broncos are livid information of their newly-formed partnership with the New Zealand Rugby Union is out in the open.
Brisbane's Courier Mail today revealed the NRL club is joining forces with New Zealand rugby HQ on a development level.
Broncos representatives met with NZRU officials two weeks ago, following a trip across the Tasman from rugby officials to the NRL club's training base in May.
A Broncos spokesperson says they're furious details of the relationship got out as they believe it's a massive advantage over rival clubs.
The Courier Mail said the deal was "a bi-partisan move designed for information sharing and improving development structures."
The Broncos recruitment and development has been heavily criticised in recent years for failing to identify top talent such as Cooper Cronk, Ben Barba, Cameron Smith, Johnathan Thurston and others.
Broncos coach Anthony Griffin said the initial foray into information sharing between the two unions had been successful.
"We had them here early in the year and we were only too happy to go back. It's an opportunity for us to learn from another successful organisation."
He said the two brands had much in common and were respected brands "synonymous with success".
Broncos development boss Brendan Barlow said: "The NZRU do things well, they are a successful organisation and we just found between the two of us it is a good relationship to have.
"There is a mutual respect there as successful sporting franchises. We have both got barriers and hurdles and we highlighted a few ideas and strategies to overcome them.
"It started informally with a chit-chat and now we look at each other's facilities and offices with a particular focus on elite player development."
He said the Broncos were not looking to steal or attract NZ rugby's top talent but had spent a week looking at the NZRU's development programs.
"They were honest with how they undertake their business, there was not a degree of arrogance, they were keen to share ideas and that's great for both of us."
