New Zealand's power and class eventually shone through as they wore down brave Namibia 71-9 in Tokyo.
Namibia battled and matched the All Blacks early on and New Zealand led only 10-9 after half an hour before stepping up their game to break clear and run in 11 tries as they won the last 50 minutes 61-0.
Sevu Reece, Anton Lienert-Brown and Ben Smith all crossed for a pair of tries, with Angus Ta'ava, Joe Moody, Sam Whitelock, Jordie Barrett and TJ Perenara also touching down.
Barrett added eight conversions for a personal haul of 21 points.
Damian Stevens kicked Namibia into an early lead with a penalty for hands in the ruck before New Zealand scored their first try after five minutes.
Barrett's cross-field kick was collected by Reece to go in on the right and they went over again midway through the half through Lienert-Brown, who stretched clear of the Namibian defence to touch down.
The Welwitschias continued to battle and compete with the All Blacks and came back to within a point through a pair of Stevens penalties.
New Zealand were reduced to 14 men when prop Nepo Laulala was sent to the sin-bin after making contact with the head of JC Greyling in the tackle.
Prop Ta'avao went over under the posts for his first Test try with Barrett converting.
The bonus point was secured when Smith powered over after a dominating scrum when Jack Goodhue popped the ball up to him to send the All Blacks into the break with a 24-9 lead.
New Zealand broke the game open after the interval with seven more tries.
Moody went over on the right after another domination scrum and Barrett sent over his third conversion.
Lienert-Brown claimed his second try of the game after Barrett weaved his way through a series of Namibian tackles and spun the ball wide for him to touch down.
Reece capped a textbook All Blacks move as they spun the ball wide for the speedy winger to go in.
Captain Whitelock then made it four tries in 16 minutes since half-time when he scored at the base of the upright from another powerful forward surge.
Smith went over for his second try of the game 13 minutes from the end as quick hands kept the ball alive and the full-back crashed over in the corner.
Ofa Tuungafasi became the second New Zealander to be sent to the sin-bin eight minutes from time for a swinging arm to the head in the tackle.
Barrett crossed for the 10th try as New Zealand surged forward after a line-out before Perenara wrapped it up with a stunning effort after picking up a behind the back pass from Brad Weber and surging through three tackles to brilliantly touch down in the corner.
New Zealand coach Steve Hansen was full of praise for Jordie Barrett's performance at fly-half in the 71-9 victory over Namibia.
Barrett has played the majority of his international career at full-back or on the wing but made his first appearance at number 10 for the All Blacks in Tokyo.
New Zealand named only two specialist fly-halves in their World Cup squad in Richie Mo'unga and Beauden Barrett, meaning the utility back was given the opportunity in the pivotal role.
And Barrett responded with a 21-point haul from a try and eight conversions.
Hansen said: "I was really pleased with Jordie Barrett at 10, (he) played very, very well.
"To be the third-choice first-five (fly-half), and our two superstar first-fives not playing. He got us round the back well. We ended up scoring (11) tries so there's a lot to like about it."
Despite the comfortable win, Hansen was not happy with his side's first-half display as they led only 10-9 with 30 minutes played.
He said: "The first half was pretty disappointing. We didn't turn up with the right attitude and Namibia made us pay for that. It's a good lesson, isn't it?
"Second half, there was pretty good stuff in it.
"It didn't happen in the first half because we had a poor attitude. They had more intent than us and played better than us in the first half.
"We came out in the second half and sorted that out at half-time and came out and played well."
Namibia coach Phil Davies could not have asked any more of his team despite the heavy defeat.
He said: "I'm very proud of the effort we put in. Particularly our ball retention and line breaks in the first half.
"We knew we were playing against the best team in the competition, the current champions but we gave it all we could. I couldn't ask any more of our players. We're very proud of them.
"The scoreboard looks a bit painful but there was lots to take out of the match.
"To play against New Zealand or at the World Cup is a fantastic opportunity and challenge. That's what we talked about. Taking on the challenge and embracing the opportunity."
