Martin Corry has admitted the first Test demise of the British & Lions 'was not a performance we can be proud of.'
England number eight Corry stood in as captain after Brian O'Driscoll was forced out of the 21-3 defeat at Jade Stadium with a dislocated shoulder.
O'Driscoll is now out of the tour, together with fellow injury victims flanker Richard Hill (twisted knee) and centre Tom Shanklin (knee inflammation).
"From all the 15 players who were on the field at any one time, we were all under par," said Corry.
"It is a case of not hiding - we were all poor. That is not a performance we can be proud of. Representing the Lions, you want to have fond memories, but today wasn't one of them.
"This is a huge occasion for us - just look at the tremendous support we've got here. This is the reason we put ourselves through all the training to be on a stage like this one, but we just didn't do it.
"The All Blacks were very good - they played an exceptional game - but we've got to improve our performance so much on today."
The Lions' major problem was the lineout, eight of which they lost on their own throw, while they also missed 20 tackles - 14 more than New Zealand - and made just one clean line-break in the whole match.
Asked to explain the lineout problems, lock Paul O'Connell said: "It was a few missed calls, and it just got worse as we went on.
"Every lineout has a day like that, and we will put it behind us. There is nothing that can't be fixed."
Welsh back-row forward Ryan Jones, who replaced Hill just 18 minutes into the action, typified the Lions' determination to bounce back from a tough experience in equally testing weather conditions.
"We can't fly out another 22 players, it's down to us," Jones said. "I certainly know if I am involved next week, I will give 100 per cent again.
"That is the attitude of the boys - we are all competitive people by nature. No-one likes losing, and we've lost to the better team on the day and there is no getting away from that.
"We have to front up. If it's 1-1 next week, then game on. If it's 2-0, then that is life and that's sport.
"We have to move on, and the biggest thing is not to let ourselves down. We have come out here and are playing against arguably the best team in the world, and we want to put on one of the best performances in the world.
"There are no excuses, and we are not going to hide. We've just got to go back to the drawing board."
