Centre Emily Scarratt scored all of England's points as they claimed a tense 13-7 win over France in their women's Rugby World Cup pool match in Whangarei.
It was England's 27th consecutive test win.
England dominated territory and possession, but France stayed in the contest to the end with superb defence as Scarratt managed a converted try and two penalties.
France's lone try came from flanker Gaelle Hermet as they spent the majority of the match on the back foot, but troubled England when they did get possession and took the ball through the phases.
England had smashed Fiji 84-19 in their tournament opener, but France provided a much sterner examination with their organised defence and bravery.
"There is not much between us and France, and the last few matches have come down to fine margins," England captain Sarah Hunter said post-match presentation.
England's final pool match is against South Africa while France play Fiji.
In Saturday's other matches Australia edged out Scotland 14-12 and the United States beat Japan 30-17.
