England have committed to playing more aggressively under head coach Jon Lewis, and Knight wants to see her side maintain the same approach in the longer format.
“Our aim is to always be positive but in ODIs you do have that added time to read situations,” she added.
“I don’t think we got that tempo right in New Zealand, so hopefully we can show how we want to play here.”
Opener Tammy Beaumont and seamer Kate Cross join the squad after missing the T20 series, while England will have to find a way to balance the side with all-rounder Nat Sciver-Brunt still unable to bowl.
England played three spinners in the T20s, with Sarah Glenn, Sophie Ecclestone and Charlie Dean all in excellent form.
“We’ve not really played all three of them at the same time in 50-over cricket, but collectively they’ve been so good, it would be so hard to leave one of them out,” said Knight.
“But with our batting we want to be positive and have that depth, so the balance of the side is something we’re going to consider.”
