Johannesburg: South Africa's bowlers struck back hard as New Zealand's batsmen struggled on the second day of the first Test at the Wanderers Stadium.
New Zealand were 97 for seven at lunch in reply to South Africa's first innings total of 226.
Dale Steyn and Jacques Kallis both took two wickets in morning session when New Zealand could score only 56 runs for the loss of five wickets.
Makhaya Ntini and Andre Nel also bowled well as the New Zealand were kept under pressure throughout the morning.
It brought South Africa right back into the match after a disappointing batting performance Thursday.
Steyn quickly accounted for nightwatchman Shane Bond, bowling him with a yorker, before Ntini claimed the crucial wicket of Stephen Fleming, who was well caught by AB de Villiers diving to his left at third slip, for 40.
Scott Styris and Ross Taylor eked out 19 runs in 10 overs before Styris was caught at first slip by South African captain Graeme Smith off Kallis.
Jacob Oram fell in the next over when he was forced onto the back foot by Steyn and edged a lifting delivery to Kallis at second slip. Steyn had figures of three for 32 at the break after taking one of the two wickets which fell Thursday.
Test debutant Taylor made the second highest score of 15 before slashing Kallis to gully.
New Zealand's collapse left wicketkeeper Brendon McCullum and captain Daniel Vettori as the last two reputable batsmen.
