Kane Williamson leads New Zealand fightback vs South Africa

Morne Morkel is ready for his Test cricket return

South Africa to have a first innings lead by day's end.

South African bowling unit had to toil hard for their wickets in the hour after Lunch but they did pick up three crucial ones later - including the well-settled duo of Williamson and Watling - to ensure the hosts don't build a massive lead.

The first test between New Zealand and South Africa held at at the University Oval in Dunedin has been delayed due after a fire alarm went off in the main grandstand on March 10, forcing an evacuation of the entire venue.

Left-armers Trent Boult and Wagner did the early damage for New Zealand with Boult's first nine overs claiming the wicket of Stephen Cook and yielding only eight runs.

Then Ross Taylor, who retired hurt on 8 after suffering a calf injury Thursday, returned to the crease unexpectedly and added a further 7 runs before ending with an unusual not out against his name.

Kane Williamson's 16th test century helped New Zealand to 341 in reply to South Africa's first innings of 308 - a slight but significant lead of 33 runs in a match which has been in the balance since the first day.

That dismissal ended a neat 104-run partnership with Temba Bavuma (52), whose own contribution was not insignificant in South Africa's recovery to a respectable score, and heralded a collapse that put New Zealand back in the game.

Under Faf du Plessis' captaincy, South Africa have won three successive Test series. It was in the 86th over eventually that South Africa opted for it and Kagiso Rabada got the breakthrough in the 93rd with the key wicket of Williamson.

A chanceless captain's knock by the stylish Kane Williamson (78 not out) guided New Zealand to a strong position at stumps on the second day of this old-fashioned Test match.

This is the first of three Tests.

BJ Watling, who contributed to New Zealand's total with 50, believed a result was still possible with "one insane session" that could change the balance.
