Last year's tour to England was also underwhelming, as a depleted Kiwis side (without Johnson, Kieran Foran and Simon Mannering, among others) lost the test series 2-1 and struggled to get their attack going for the whole trip.
"It's a very tough place to go," said former Kiwis coach Frank Endacott, who fashioned an impressive record against Great Britain.
"The timing doesn't help - it's at the end of the year when the players are pretty weary - it's coming into winter so it's cold and the conditions aren't easy.
"And the crowds are right on top of you. They create an amazing atmosphere but it can be hard for young players."
Endacott never lost a test against Great Britain and masterminded the historic 1998 tour of England, when his team won the series 2-0 (the third test was drawn), becoming the first Kiwis touring side to not lose a test in England.
Times have moved on - there are now many more English players in the NRL - but some principles haven't changed.
"Touring teams normally get better as the trip goes on," said Endacott. "But it needs to be a unified group. Living together, travelling together, playing together ... everyone needs to be buying into the same message. And discipline is key. Any 50-50 penalties will go against you, due to the influence of the crowd."
He said England can never be underestimated, despite the apparent decline of Super League over the past few years.
"People will look at Super League and think that the standard has dropped, and it probably has. But there are still plenty of good individual players around that can be moulded into a good team," said Endacott.
"You can't take them lightly at all, especially with a coach like Wayne Bennett on the scene."
