Reynolds had no qualms about being behind Marshall and was adamant his 33-year- old teammate had been so good he deserved a return to the New Zealand team, which is coming off a disastrous World Cup campaign.
"Yeah, 100 per cent," Reynolds said when asked if Marshall should be the Kiwis No.6 for their mid-year Test against England.
"He's playing good footy. I'm not sure who he's up against for that position. On form, it'd be silly not to.
"Just being around him, he's just got a lot of footy knowledge. I think that can help New Zealand at the moment.
"If you looks at the Warriors' form, they're are at the best they've been in five years. And they make up a lot of the New Zealand team. If you throw in someone like him, I think they'd be a great side."
Marshall was essentially banished from the Kiwis side under former coaches Stephen Kearney and David Kidwell.
After Kidwell stepped down following their disastrous World Cup campaign, Geoff Toovey, Laurie Daley, Michael Maguire are among the contenders to take over as coach.
Marshall's chances of earning a Test cap for the first time since 2012 will depend on who steps in, however there's little doubt he's out-performing fellow contenders Kieran Foran, Kodi Nikorima and Te Maire Martin.
