Michael Clarke and Marcus North moved Australia into an even more dominant position of 4-405 at lunch in the second day of the first Test against New Zealand at the Basin Reserve in Wellington.
Clarke (153 not out) reached his 150, his highest score against New Zealand, shortly before the break, reaching the milestone in 228 balls with 19 fours and two sixes.
Meanwhile North (84 not out) has flown under the radar but was equally as impressive during the morning's play and looked likely to reach his first century against New Zealand.
The pair notched a record fifth-wicket partnership against New Zealand, passing the old record of 214 to reach 229 between them by lunch, after resuming from a good first day's play with Australia on 4-316.
New Zealand seamer Daryl Tuffey continued to bowl conservatively, but there has been little to suggest that either batsmen is looking threatened by the Kiwi bowling attack on a pitch that looks to be drying out and will allow plenty more runs to be scored.
On the first day's play, Clarke, with help from the powerful hitting of North, got the tourists out of an uncomfortable position when they were sitting on 4-176.
The pair forged an unbeaten 140-run partnership on the first day to put the visiting side in control of the match.
Earlier on the opening day, Clarke and Simon Katich (79) saw off the New Zealand bowlers in style, with the latter looking strong for the majority of the day, reaching his 21st half-century before being trapped lbw by Kiwi debutant Brent Arnel (2-70).
Tuffey bowled extremely well for New Zealand and, while he failed to claim a wicket, gave away just 35 runs off his 16 overs.
However, it was Arnel that proved the most destructive of the Kiwi bowlers as he claimed openers Katich and Phil Hughes.
