The All Blacks extended their winning streak over the Wallabies to 10 straight wins with a 22-23 victory over the Wallabies in Sydney which gives the All Blacks a Grand Slam.
The All Blacks are the first team to have ever gone through an extended TriNations campaign unbeaten - but it looked like their winning streak would come to an end with 15 minutes to go in this match.
The Wallabies scored the only try of the first half through James O'Connor to lead 14-6 at half time after Wallaby kicker Matt Giteau had missed three kicks at goal.
Earlier Lachlan Turner looked to have given the Wallabies the perfect start in the fourth minute when he scored a try in the corner. Replays however showed that he had put a foot in touch.
The Wallabies picked up where they left off in the second half as Adam Ashley-Cooper dummied a pass and scored the second try of the match only for Giteau to miss the conversion.
The All Blacks were the next to score a try through captain Richie McCaw after the Wallabies had extended their lead to 22-9.
Weepu converted and the All Blacks were trailing by 6.
Another try by Kieran Read which was converted by Piri Weepu put the All Blacks in front after they had scored 17 unanswered points.
Australia led 14-6 at halftime and were 13 points in front after winning most of the battles against the world's number one team, but the physical effort of three consecutive weekends of Test matches took its toll.
The All Blacks' triumph was a great tonic for their country after last weekend's Christchurch quake, New Zealand's biggest in decades, left an estimated 100,000 buildings damaged, even though nobody was killed.
"We were chasing the game a bit early but the great thing was that we didn't worry about the scoreboard but more about getting some field position and to start building pressure," said McCaw, who became New Zealand's most-capped Test skipper with his 52nd appearance.
"Once we started to do that our confidence grew and the things that we had practised began to work and for the last 20 minutes it felt like we had the momentum."
The All Blacks finished the six matches of the southern hemisphere championship scoring a record 184 points and 22 tries.
They had already clinched the trans-Tasman Bledisloe Cup for an eighth straight year after winning 49-28 in Melbourne and 20-10 in Christchurch earlier in the season.
"In our last two games with them our opponents have responded, they got their hands on the ball, built some pressure and we left some points out there on the park which proved the difference," Wallabies' coach Robbie Deans said.
Wallabies' skipper Rocky Elsom agreed: "They finished stronger than us with those two tries at the end, you couldn't argue with that."
Scrum-half Piri Weepu's goalkicking proved the difference as he landed three penalties and two conversions, while Wallaby Matt Giteau could only score with three of his seven kicks before he was replaced by Kurtley Beale.
Australia had more possession and territory and led through the only try of the opening half to winger James O'Connor.
The All Black defence was breached in the 16th minute when number eight Ben McCalman picked up the ball from the back of the scrum and made a break.
McCalman drew the last line of defence to send O'Connor racing over in the right-hand corner.
Adam Ashley-Cooper scored Australia's second try seven minutes after halftime off a long pass from scrumhalf Will Genia to push the home side's advantage to 19-6.
Weepu kept the All Blacks within range at 19-9 with his third penalty.
Beale took over the goalkicking duties from the misfiring Giteau and landed a penalty to give the Wallabies a 13 point lead heading into the final 20 minutes.
The All Blacks were rewarded for their incessant pressure on the Wallabies' line when Read and McCaw combined off a scrum win for the All Blacks skipper to score.
Weepu converted for New Zealand to trail 22-16 with 11 minutes left.
The All Blacks continued to turn the screw and posted their second try by Reid with Weepu's conversion edging them in front 23-22 with seven minutes left.
La Nouvelle-Zélande a battu l'Australie sur le score étriqué de 23 à 22. C'est la première fois qu'une nation remporte tous ses matchs depuis la mise en place de la version étendue à six matchs par équipe au sein des Tri Nations. C'est aussi le quatrième Grand Chelem de son histoire pour les Kiwis. Très longtemps menés au score, 19 à 6, puis 22 à 9, les All Blacks ont su retourner la situation grâce à deux essais transformés de Richie Mc Caw et de Kieran Read en fin de rencontre. Ils reproduisent pour la deuxième fois consécutive le même scénario, le précédent contre l'Afrique du Sud. Les hommes de Graham Henry ont effectué un retour en fin de rencontre.
