"I'm not unhappy with it. I think three weeks is not enough, and particularly they did it after you'd selected your team - who knows you may have chosen to pick more attacking players," she said.
However, what was done was done and Waetford was taking a practical view to the news.
"Just get on with it. I certainly gave them feedback on how I felt, and they'll just say everyone is in the same boat."
The rule changes, which officially come into play on September 1, come courtesy of the International Hockey Federation (FIH) which stipulated that all territories adapt them.
New Zealand players and fans are getting a taste of the new format in the NHL.
Rule changes aside, Waetford is confident her team can replicate their form from 2012 that saw them finish fourth - the highest the Northland women's team has finished.
Helping Waetford's confidence is the return of Black Sticks Stacey Michelsen and Brooke Neal, who will rejoin London Olympics teammates Ella Gunson and Alana Millington.
Also in the fold are former Black Sticks Jasmin McQuinn and Laura Douglas, who will team up with two international guest players in the form of Esther Hotham and Maddison Rosser, both from New South Wales' winning under-21 side.
For the Northland men's team, it will be a former representative trying to trip up his old team in the form of Mike Delany.
The Northland men's team, though, boasts a mixture of experience and youth which will be on its side this afternoon.
The team includes Northland 100 cap veterans Sam Webb and Dion Watts being joined by newcomers Harrison Lamb and James Houston.
International guest players are Joshua Mynott and Matthew Argent from Queensland.
The Northland teams face Auckland tomorrow at 12pm and 2pm.
