The Basin was an off match for the world's No2 batsman. These things happen. But if New Zealand are to come up with enough runs for the bowlers to work with, you suspect Kane Williamson is the key figure. Since his century at Perth in November, there's a belief Australia have worked on a plan to him. They've had some success, too. Back Williamson to work a way out of it.
3 Productivity at No6 and 7
Time for Corey Anderson and BJ Watling to show their mettle. Watling's been ordinary since being in Australia. The players love having him in there, but he has to deliver. It has been 10 innings since he passed 35; since the start of the Australian trip he's averaging 17 in six tests. Anderson played his first test in nine months at the Basin. He averages 30 but his allrounder role is pivotal. With Brendon McCullum out of touch, Henry Nicholls finding his way and no Ross Taylor, Nos6 and 7 must get runs.
4 Swinging along
Tim Southee and Trent Boult have fine test records, but they're ordinary against Australia. They were unable to find swing at the Basin. They must rediscover it this weekend to put some skids under Australia's batting order. Whether Neil Wagner or Matt Henry, or both, make the final XI, Southee and Boult are the country's swing kingpins. The Hagley Oval pitch promises help. They must grab it.
5 Final blast from the skipper
This might be asking a bit much as McCullum looks as if his flame has gone out. But this is the final outing and you know he'll be busting to deliver. If he can, consider the galvanising effect it could have.
