South Africa captain Dean Elgar suggested that his side were trying too hard to force a result against New Zealand after they slumped to a historic loss in the first Test.

The Black Caps won by an innings and 276 runs, as the visitors were bowled all out for 95 and 111 respectively in what was their second-worst-ever defeat.

The triumph was New Zealand's first in the Test arena against South Africa since 2004, a run remarkably dating back 16 matches.

Elgar, however, refused to lay the blame at the feet of South Africa's disrupted build-up, with no warm-up matches having been held for the two-match tour, stressing that his side need to hold themselves accountable.

"I can't say it was nerves," the opener told reporters. "We were so deep into the game, those nerves were out of our system.

"It's extremely difficult to build pressure when runs are being scored on both sides of the wicket. It also boils down to guys trying too hard. The harder you try, the more you fail.

"I am not going to use quarantine as an excuse. We are here to represent our country, and we need to be firing by the time match day comes. If that is an excuse, it's a very weak excuse to be using."

Elgar offered his backing to number three Aiden Markram however, though conceded that the batsman's fall in form over recent months at Test level is a concern.

"It's not foreign that he has been struggling," he added said.

"Maybe it's the mental game he is fighting. Naturally he is a gifted player and he is one score away from turning things around."

Stand-in skipper Latham hails depth power

New Zealand's work in Christchurch was doubly impressive given the absence of Kane Williamson and Trent Boult, with the game the first time the Black Caps have played a Test without them or Ross Taylor for 14 years.

Stand-in captain Tom Latham was quick to hail the strength in reserve on show, adding: "It is testament to the depth in New Zealand cricket that guys who haven't played a lot can step up and come up and perform straight away."

Proteas make unwanted history

Aside from suffering their second-worst loss in Test cricket – behind only their innings and 360 runs loss to Australia in 2002 – South Africa also wrote themselves into some more unwanted record books.

Their result was the biggest margin of defeat suffered by a Test side in the past decade, while no South Africa player individually scored more than New Zealand number 11 Matt Henry did in his lone knock, with 58 – just the fifth time the feat has been achieved.
