England claimed another ruthless, record victory against New Zealand as Amy Cokayne scored a hat-trick in Northampton to seal back-to-back wins.
The Black Ferns are expected to be one of England's main World Cup rivals, but could not respond as the Red Roses scored four first-half tries.
New Zealand scored three tries after the break, but England crossed three more times to remain world number ones.
The victory breaks the record winning margin set in last weekend's 43-12 win.
England wear dominance with ease against world champions
Newly-appointed England captain Poppy Cleall had expected New Zealand to respond with a lot of "emotional energy" after last weekend's heavy defeat and to begin with it looked like the Black Ferns might deliver.
The visitors won a scrum penalty and threatened up front, but a moment of individual brilliance from England centre Helena Rowland seemed to break the spell.
Showing her sevens prowess, Rowland cut through New Zealand's defensive line with ease and from there England stamped out any sign of a Black Ferns challenge.
The Red Roses forwards soon put their mark on the game too as Cokayne took the ball over in a maul for her first try.
As New Zealand made an increasing number of errors, Cleall blew a hole in their defence and Ellie Kildunne profited as she crossed on the left.
Where there might have been a sense of disbelief in England's early lead over New Zealand in the first game, this time the Red Roses wore their dominance with ease.
They were boosted by a penalty try after New Zealand scrum-half Kendra Cocksedge was shown yellow for a deliberate knock-on.
The Black Ferns made their way into England's 22 around the 20-minute mark but despite their 21-point lead the hosts were as relentless as ever.
The game slowed somewhat before Cokayne went over in a maul for the second time to further assert England's lead over the five-time world champions before the break.
