South Africa secured a drawn series with New Zealand as they clinched a 198-run win on the final day of the second Test in Christchurch.

New Zealand began day five on 94-4 but their hopes of holding on to seal a series win were dashed by the Proteas' attack.

Devon Conway was the man holding the New Zealand second innings together, resuming unbeaten on 60.

But he fell eight runs shy of a century and his exit opened the floodgates as the emerging Marco Jansen excelled with the ball and Keshav Maharaj claimed the final wicket to ensure the spoils were shared.

Lutho Sipamla removed Conway when he trapped him lbw with a full delivery and the Black Caps' resistance was never the same thereafter.

Tom Blundell (44) missed out on a half-century and, more importantly, removed himself as a set batsman when his half-hearted pull shot off Jansen only went as far as Temba Bavuma at midwicket.

Left-armer Jansen then removed Colin de Grandhomme, scorer of an unbeaten century in the first innings, with a short ball, leaving the tail to try to prolong the inevitable.

Kagiso Rabada ran to deep leg side to help Jansen secure his third by dismissing Kyle Jamieson before Rabada got in the act himself, drawing an edge to midwicket from Tim Southee.

Rain arrived to frustrate South Africa and force umpires to call an early tea, but the Proteas' wait for the decisive wicket was ended when Maharaj trapped Matt Henry in front for a duck.

More Marco magic

After being limited to two wickets in the first Test, Jansen was back to more prolific form here, following up 4-98 in the first innings with 3-63 in the second. He has taken at least five wickets in all but one of his five Test matches and claimed seven in three of his last four.

Rabada (3-46) finished with eight wickets in the match while spinner Maharaj provided crucial support with 3-75.

Elgar stays unbeaten

Having overseen a victory in the West Indies and a home win over India, a drawn series in New Zealand means Dean Elgar is still yet to lose a series as South Africa captain. If a young attack keeps performing at this level, he will be able to look forward to plenty more victories.
