Another solid stat from Nick: Comparison of time spent in the sin bin chair to time spent on Aaron Smith's hairdressing chair 30:1000 (in mins)
Dan Carter has just been thumped in a dangerous tackle and the ref has blown it up to check out the replay.
Paula Ngauamo has been sent to the bin for the tackle on Carter. He picked him up and dumped him, though it didn't look to dissimilar to Ben Smith's tackle in the first half.
Into the final 10 minutes now and the ABs have set up a lineout drive 10m out.
TRY ALL BLACKS! Sam Cane has bundled his way over from close range.
Sam Cane has 10 test tries in just 28 games, and only 13 starts
Carter slots the conversion and the All Blacks now lead 42-9.
73 MINS: ALL BLACKS 42 TONGA 9
With seven minutes left to play Tonga have a penalty 22m out. They kick for touch, the crowd give them a mighty cheer. Can they score a try?
It's not looking good. The ABs defence stands very firm and Tonga are forced deep back to halfway.
75 MINS: ALL BLACKS 42 TONGA 9
Five minutes to go and Tonga have a scrum on halfway.
The crowd are urging Tonga forward as they approach the line, but the ball has been turned over and Barret clears way down field.
Ma'a Nonu has scored his 30th try in his 100th game. What a great way for the All Blacks to end this match.
They ABs broke through Milner-Skudder who once again showed electric pace down the left wing before drawing a defender and passing to Nonu who dived over the line with a huge smile on his face.
Ma'a Nonu is now 10th all-time on the All Blacks try scoring ladder with 30 test tries, one ahead of Dan Carter and Sitiveni Sivivatu
Carter misses his first kick of the night and the All Blacks now lead 47-9 with two minutes remaining.
The first half was messy, but the All Blacks have undoubtedly answered their critics in the second. They have torn apart a tiring Tongan defence and found that cohesion they were lacking.
Time is up on the clock, Tonga still have possession on halfway and are into their 11th phase.
It's all over. The All Blacks have beaten Tonga 47-9.
FINAL SCORE: NEW ZEALAND 47 TONGA 9
Thanks for joining us today in our live blog. Stick around because we have a lot coming up. We will have the winner of TABs $100 voucher, the reaction from the players and coaches, video highlight and a Q and A with Herald rugby expert Wynne Gray.
From Gregor Paul in Newcastle: It took a while, had a few iffy bits along the way and wasn't quite the emphatic statement they were hoping for, but the All Blacks did at least run into more convincing form in Newcastle.
They will be happy how they left things in the end. By the final quarter they were whizzing along quite impressively and their pass and catch was on the money. They looked confident, eager and ready to get into business.
Gregor: Certainly the rest of the quarterfinalists will have watched that final quarter with an element of concern that the All Blacks are cranking the handle. They are starting to play like the All Blacks and that's the news no one outside of New Zealand wanted to hear.
The reason it took them a while to get there was because Tonga did exactly what it said on the tin: they scrummaged superbly, tackled things to within an inch of their life and stayed in the contest by being physical across the park.
Kieran Read: We certainly had a very tough game today which is just what you need at this stage of the tournament. There are things we can work on and they put us under a lot of pressure and we know it's going to be like that last week. But we fought back really well in the second half.
Kieran Read:Our work up front needs to probably improve especially in that first half but we'll re-group and we're glad to be where we are. There are teams that won't be here next week.
