New Zealand took the honours, just, on the second test of the second test against Australia at the Waca today.
New Zealand had reached 140 for two at stumps today in reply to Australia's 559 for nine declared, their fifth highest total in transtasman tests.
Kane Williamson was on 70, which included 10 fours, and is within sight of what would be his 12th test century, and Ross Taylor had reached a steady 26.
New Zealand's immediate target tomorrow will be reaching 360 to avoid having to follow on.
When he completed his half century, with a rasping cover drive off left arm quick Mitchell Johnson, it was the in-form Williamson's eighth 50-plus innings in his last 12 in tests.
