Mes has been included as one of four training partners for the tour, which includes tests against England and Jamaica - the Ferns' final outings before next year's Commonwealth Games.
But although Taumaunu is warning the "gritty" Mes is still in the early stages of her comeback, she has included the young shooter in the group so she can work under Silver Ferns assistant and specialist shooting coach Vicki Wilson.
Mes is one of two players the Silver Ferns are welcoming back from injury, with Pulse midcourter Camilla Lees rejoining after missing this year's international season with a stress fracture in her foot. Lees has been included in the test side at the expense of Courtney Tairi, who will still tour as a training partner. Steel midcourter Shannon Francois retains her place in the 12 after impressing in the Constellation Cup series.
Under-21 stars Malia Paseka and Phoenix Karaka will also tour with the senior squad as training partners after impressing in New Zealand's shock victory at the World Youth Cup in August.
"They're a very long shot to make the Commonwealth Games squad, but ... they need to be ready," said Taumaunu.
Former Ferns defender and new mum Anna Harrison was unavailable.
