New Zealand captain Kieran Read feels his team need to "go back to the drawing board" despite beating Wales 39-21 in Auckland on Saturday.
Wales led 15-18 at half-time after a superb first-half at Eden Park, as the All Blacks looked rusty in their first international of the season.
But after the break the world champions clicked into gear as they took a 1-0 lead in the series heading to Wellington, with Read relieved.
"We'll take it, we've got plenty to work on for next week," he said before adding he was happy to start his tenure as captain with a win.
"It's certainly a pretty proud moment to run out in front of the boys. But it's a good team, we're just building. We'll get back to the drawing board on Monday and we know we've got a big test again down in Wellington."
He continued: "The boys who came on I think had a big impact in this game. So the bench did really well.
Meanwhile, Wales captain Sam Warburton praised his team for their brave style in a much-improved showing after their loss at Twickenham.
"We knew we couldn't come to a place like New Zealand and be conservative and hope to win by edging penalty kicks, we knew we had to score tries," he said.
"You've got to be pretty brave in terms of the decisions you make, try and throw the ball a bit, and we did that probably more so than we would back in the northern hemisphere. And it paid off for us, we got some pretty good tries, just a few defensive issues we need to tighten up. And disappointing to give away seven at the end, which makes the scoreboard look a little bit ugly.
"Our counter attack was pretty good in patches, but credit to New Zealand, you make one mistake and it turns into seven points, and two mistakes turns into 14 points, they're pretty ruthless."
He added: "We took some chances and it paid off. We're working with the world champions here, two-time world champions, and we gave it a good crack, but it's not good enough for us, we want to come here and [there's a] massive focus on getting a win.
"We're tired of being heroic losers, I know everyone back home feels the same, so we're doing everything we can behind closed doors to get a win, and it's something we're desperate to do."
