Steve Hansen has called up the Crusaders' Tom Taylor as Cruden's replacement, but may prefer to have the experience of 23-times capped Barrett in the starting line-up against the Pumas on Saturday.
And Barrett, who's New Zealand side host the British and Irish Lions in 2017, knows what a big chance he may have been presented against the team he started against in Napier three weeks ago.
"Potentially it's a great opportunity for me," Barrett told Fairfax Media. "I'll just prepare as I normally do. It's another challenge, Argentina at home.
"It's another step up, especially [when rainy] conditions like [in Napier] make it difficult. It gives me a bit of confidence, if selected, that I'm used to playing them.
"Hopefully with the weather like it is at the moment we can expect this and play an expansive game."
