New Zealand coach Mike Hesson was critical of his side after day two of the second Test in South Africa.
The Black Caps crumbled in Port Elizabeth as three Proteas centuries helped the hosts post a daunting 525-8 before declaring and turning the pressure on the tourists.
Hesson's men did not fare well in their reply - Dale Steyn, Rory Kleinveldt and Robin Peterson picking up two wickets apiece to reduce New Zealand to 47-6.
Hesson said: "We knew what we were confronted with. When we got under pressure, we weren't able to cope.
"I think we all share the load, to be honest. This test match and the last test match we haven't been up to it. South Africa is a very tough place to tour.
"They're the world's No. 1 side for a reason. At the moment we're ranked eighth in the world for a reason. We're struggling. The players are trying their very best and they're being outclassed."
By contrast, Faf du Plessis, who struck his second century for the hosts, was in positive mood - saying: "We did everything right so it's very close to a perfect day."
