Richie McCaw says the solution to stopping top All Blacks taking up big deals overseas isn't foolproof but it is effective.
"You've just got to make it really hard for guys to make that decision to go overseas."
The former All Blacks captain told the New Zealand Herald keeping top talent on Kiwi shores has always been an issue but it's just part of life for New Zealand Rugby.
The governing body may not be able to match European clubs dollar-for-dollar, but McCaw believes if guys get a good taste of life in the All Blacks, such as team culture, history and success, it makes other factors such as money less important.
"We've always said having an environment that's really enjoyable and fulfilling, [where] you get looked after, and the chance to play for the All Blacks, that's the things that we've got in our favour as New Zealand Rugby.
"And some will [leave], and rightly so if that's the right thing for them. But if we keep the environment good and the All Blacks successful, it's quite a hard team – when you've had a taste of it – to turn your back on.
"We've just got to keep hopefully inspiring people that want to perform in the black jersey because I think it's a pretty big carrot to stay here."
McCaw played 148 Tests for the All Blacks, becoming the first international captain to win two World Cups after he led the New Zealand side to titles in 2011 and 2015.
He said in the span of his 16-year career he never felt a desire to head offshore, saying it was always a "pretty easy decision" to stay here.
