Added to that is the fact that the side's only Olympian Alana Millington, won't be back in time for the weekend's fixtures after taking a short break in Europe after the Olympics.
"The only positive from that is that all of the Black Sticks are out this weekend and Auckland and North Harbour have more of them than us," Gibbs reasoned.
This year's team has been weakened by the loss of Olympians Charlotte Harrison, Ella Gunson, and Stacy Michelsen, who are all unavailable this year - but their absence will give others opportunity.
Gibbs is still confident his side will do well in the tournament and is expecting a lot from O'Donnell and fellow imports Shereena Nana and Jenny Griffin from Auckland. The women's game against Auckland on Saturday at the Northland ITM Hockey Stadium is at 12pm, followed by the men at 2pm. Both sides travel to North Harbour on Sunday for their second match.
Northland Women: Alana Millington, Aleyse Emerali, Alyse Morgan, Alicia Jurisich, Alyx Pivac, Brooke Roberts, Carolyn Lancaster (RO), Elley Miller, Jade Mcleod, Jane Thompson, Jess McAlister, Jodie Nichol, Nat Newson, Nicky O'Donnell (IGP), Samaria Tugaga, Shereena Nana (GP), Jenny Griffen (GP).
