Mannering missed last year's two-one series loss to England with illness and this year's Anzac test with injury, with Storm front-rower Jesse Bromwich getting his first run as captain in the Hunter Stadium defeat under former coach Stephen Kearney.
Kidwell opted to retain Bromwich as skipper for this week's one-off test and the subsequent Four Nations campaign.
Incumbent fullback Jordan Kahu said the side were a united group under Bromwich but believes Mannering will still play a big role among the side's leadership group.
"Once he does come into camp he'll have a massive leadership role as well," said Kahu.
"Obviously he (Bromwich) was captain in the Anzac test and Jesse carries himself really well and a lot of boys look up to him.
"Everyone's behind him 100 per cent so I'm sure he'll lead the way for us."
The Kiwis had a light run yesterday and have their first full day of training today in cool conditions in Perth.
The team will arrive back in New Zealand on Sunday and have three days break before re-entering camp in Auckland.
The Kiwis open their Four Nations campaign against hosts England on October 30 (NZT) at Huddersfield, before games against Australia on November 6 and Scotland on November 12.
