Gareth Widdop in action for England during the first Test against New Zealand
McNamara has named an unchanged squad for the game following the 26-12 victory over the Kiwis in the first Test in Hull last Sunday.
England will be aiming to make up for the disappointment of their last meeting with New Zealand in the capital, the 2013 World Cup semi-final at Wembley, where Shaun Johnson broke their hearts with a last-minute try and goal.
New Zealand coach Stephen Kearney has named an unchanged starting line-up for the second Test against England at London's Olympic Stadium on Saturday.
Kearney has stuck with the team that started strongly in Sunday's first Test in Hull before being defeated 26-12.
However, he has tinkered with the bench by recalling veterans Lewis Brown and Alex Glenn in place of Kodi Nikorima and Sio Siua Taukeiaho, who made their debuts as substitutes at the KC Stadium.
"Both these guys we're bringing in were a bit unlucky to miss out the week before and offer a great deal of experience," said Kearney.
"Looking at last week's game, that will be important for us this week. Lewis has done a great job for us in the past and Alex Glenn has had a wonderful year, so it's just desserts for them.
"We're in a position where we have to perform and these guys have done it for us before."
Officials are hoping for a near-capacity crowd of just short of 50,000 for the first rugby league match to be played at the Olympic Stadium, having already posted the "house full" at Wigan for the third Test on Saturday week.
