Edwards hopes to add this trophy to the 50-over World Cup won this year
England's preparations for the inaugural Women's World Twenty20 continued smoothly with a seven-wicket win over New Zealand in Taunton.
They chose to field on a cold, overcast day at King's College and restricted the Kiwis to 122-8, new skipper Aimee Watkins top scoring with 38.
In reply England captain Charlotte Edwards shared an assured opening stand of 73 with Sarah Taylor, who made 44.
Edwards hit a four to reach fifty and another next ball to record victory.
"It's a good start," Edwards said. "We are in our own conditions and we have been playing a lot recently, so we're in good form as a team. It was a good outing for us and I'm pleased we got the result.
"We did well to restrict them to 122 and did well to get the runs and a few wickets as well. I'm looking forward to another game against Australia and hope the weather holds!"
Jenny Gunn was the pick of the England bowlers, collecting 2-13 having been brought into the attack in the last five overs, while Edwards claimed 2-15.
Elsewhere, South Africa women beat their Sri Lanka counterparts by 26 runs.
Also on Monday, West Indies women defeated their Pakistan opponents by 26 runs while Australia's clash with India at Taunton was abandoned because of rain.
