New Zealand cricket coach Mike Hesson has defended his side's lapses of judgment in the drawn first test against South Africa.
The Black Caps missed some opportunities to seize the advantage in the field and through the decision review system in the first session of the fourth day, but held parity with the tourists throughout.
The Proteas survived two failed reviews, one non-review that would have earned a wicket, and two dropped catches.
New Zealand recovered to take three wickets for 67 runs in the final session. South Africa were left on 224 for six, a lead of 191 runs, before rain washed out the final day.
The hosts suffered for their misjudgment on five occasions.
1. A failed review from Trent Boult in the 25th over, when a ball hit Jean-Paul Duminy's pad, rather than the bat, on the way through to B-J Watling's gloves.
Duminy was on two.
2. Tom Latham dropped a first-slip catch off Boult in the 29th over, when Duminy was six.
3. No review was taken, when Jeetan Patel hit Duminy (20) on the back leg in the 38th over, which, in hindsight, the ball tracker showed hitting the stumps.
4. An lbw review was taken against Duminy (20) in the 40th over, when an inside edge hit his pad.
5. Elgar (35) edged Jimmy Neesham in the 41st over, but the ball clipped Watling's out-stretched glove.
Neesham had two first-slip catches elude his grasp from Elgar off Patel and Mitchell Santner. One fell short; the other squirted to his left.
Elgar scored 89 and Duminy 39.
Post-match, it was suggested to Hesson that the team had "cocked-up a few DRS decisions".
"You've probably put that quite succinctly, really," Hesson quipped. "It's probably something we need to firm up on.
"With the DRS, you do need to take time to gather information. We missed out on one against Pakistan earlier in the summer, when we took half a second too long, and there's probably a couple in this series, where we let emotion take over and made instant decisions, which weren't right."
Hesson defended the work of his rejigged slip cordon in the absence of the injured Ross Taylor.
"Tom dropped one at first slip, but unless B-J grows another four inches, he's never going to catch the one, which hit the end of his fingers.
"To consider there's a whole heap [of dropped catches] is off the mark. Tom's fielded at first slip in ODI and test cricket quite a lot, and been good.
"In many ways, he had too long to think about [the spill]. In some ways, you want those to arrive quickly, so you're more instinctive."
The Wellington forecast is for rain leading up to the test start on Thursday, but fine for most of the match. The pitch is expected to be under covers for much of the build-up.
Hesson was asked whether that meant a return to an attack of three specialist pace bowlers and one specialist spinner.
"Some of the ODI wickets were under cover for a long time this summer [before games] and they spun a bit more. It's a matter of rocking up, being open-minded and seeing what we're dealing with.
"We've got a squad we think can cope with whatever we're dealt with. There's not a heck of a lot you can do if it's under covers.
"You can't put a marquee around it and dry it out."
Given the onus placed on two spinners in the Dunedin test, Jeetan Patel was New Zealand's sole presence before lunch on the fourth day, bowling three overs. He bowled 36 in total during the second innings, taking two for 72.
He was preferred as a means of taking the ball away from the left-handers.
By contrast, Mitchell Santner only bowled his first over (his sixth of the innings) at 3.37pm. He took one for 37 from 19 overs.
"They bring slightly different qualities," Hesson said, of Patel and Santner. "One [Patel] is able to bowl a lot of overs, which was required on this [Dunedin] surface and he can control the run rate.
"They offer something different to left-handers and right-handers, and one [Santner] obviously bats better than the other.
"It depends on the balance we want to go in with, rather than ranking them No.1 and No.2."
Taylor's right calf injury has ruled him out of the Wellington test. His replacement Neil Broom is set to make his debut.
Boult has travelled to Wellington, where his sore left hip and pelvis will be monitored. Tim Southee is expected to return regardless on a more seamer-friendly pitch.
If Boult does not pass muster, Matt Henry is next in line.
