Adam Voges boosted his Test average to more than 100 on Saturday as he and Usman Khawaja scored centuries to set Australia up for a huge lead in the first Test against New Zealand.
Australia were 463-6, heading New Zealand by 280 on the first innings at stumps on the second day.
Khawaja was out for a classic 140 and Voges, given a life on seven, was unbeaten on 176.
The 36-year-old Voges, in his 19th Test innings, saw his Test average rise to more than 100, bettering Don Bradman's 99.94 from an 80-innings career.
Voges has scored centuries in his last three innings, posting 269 runs not out and an unbeaten 106 against the West Indies in December.
The combined total of 551 overtakes the previous record of 497 runs between dismissals held by Sachin Tendulkar.Voges and Khawaja's firm grip on the game in a 168-run stand for the fourth wicket left New Zealand with few moments to relish on a day of toil under the baking sun.
It was a sublime partnership that lasted 50 overs and offered few chances.
BJ Watling missed a stumping opportunity when Khawaja was on 34 and Mark Craig was confident with an lbw appeal that was turned down when Khawaja was on 104.
A review showed the ball would have grazed the outside of leg stump and the umpire's original not out decision remained.
Voges had his moment of luck in the last over on day one when he was bowled by Doug Bracewell, only for umpire Richard Illingworth to wrongly call the delivery a no ball.
Since then, Voges has added 169 runs in an innings that has lasted 286 deliveries and includes 26 boundaries.
Boult hinted a fightback for New Zealand was possible with two wickets in three balls during the middle session on Saturday to remove Khawaja and Marsh and have Australia 299-5.
But the euphoria in the New Zealand camp quickly disappeared as they laboured through another 27 overs and 96 runs before Peter Nevill was the next wicket to fall.
Boult outsmarted Khawaja by bowling wide of the crease and as the left-handed batsman shaped to turn the ball to the on-side it straightened and slammed into the back pad.
Marsh was out to a spectacular catch off the second ball he faced when he drove hard at a Boult delivery, and the left-arm paceman flung himself high to his right to snare the ball in his right hand.
Boult's reaction time was measured at 0.594 of a second.
Australia had resumed the day on 147-3 and added 91, 92 and 133 in each of the three sessions on a flattening pitch.
