The ECB has made an unsuccessful request to New Zealand Cricket (NZC) to move the dates of England's upcoming women's tour, with four players deemed unavailable for the first three T20Is as a result of their Women's Premier League (WPL) commitments in India and two others pulling out of their franchise contracts.

"Yes, there are things that other boards could have done, but they're things that are totally out of our control to be honest. We've had to react to the situation as best we can it's quite a unique situation. It's quite complex we talk to everyone as individuals and work out what we think is the best plan for them."

Lewis blamed the late release of the WPL's schedule, which was decided several months after NZC had confirmed the dates of England's tour. "[The series] was in our diary for a very long period of time," he said. "The WPL dates came out very late. Moving forward, all the boards around the world will create a window for the WPL similar to the men's game."

The ECB told the eight England players with WPL contracts that to be considered for selection in the first three T20Is, they would need to leave India before the knockout stages. Jonathan Finch, the director of England women's cricket, said: "All players participating in the WPL were given our backing to remain in India for the duration of the tournament."

Lewis himself will leave the WPL after UP Warriorz's final group game on March 11, with assistant coach Ashley Noffke likely to deputise if they reach the knockout stages. "I had good discussions with the franchise," Lewis said. "Hopefully, we're in a really strong position. We've got a lot of cover in the coaching department and UP have been really accommodating."

"We tried to make sure that all the players that are in New Zealand with us will get a really fair crack, rather than worrying about Nat Sciver-Brunt getting knocked out [of the WPL] on one day, flying in three days later and taking their position in the team," Lewis said, framing the clash as "a brilliant opportunity" to test England's depth ahead of the T20 World Cup in Bangladesh later this year.
