New Zealand closed in on a massive victory inside three days in the opening Test against South Africa on Friday after taking a 387-run lead and then reducing the tourists to 34/3 on Day II of the contest.

Henry Nicholls struck 105 and Tom Blundell made 96 as the world Test champions amassed 482 all out to effectively bat South Africa out of the contest.

On the back foot since being bundled out for 95 in the first innings, South Africa’s top order collapsed for a second time at Christchurch’s Hagley Oval to finish the day 353 behind.

Temba Bavuma (22) and Rassie van der Dussen (nine) will resume on Saturday hoping to delay an imminent defeat in the first match of the two-Test series.

“It’s been outstanding the whole game and to get three (wickets) was pretty amazing,” Blundell said of their bowling effort.

“I think if we can keep this momentum going and put them under pressure, hopefully, fingers crossed, we can wrap it up tomorrow.”

South Africa’s four-man attack without a specialist spinner has looked pedestrian and they also dropped four catches to let New Zealand off the hook.

Nicholls alone was the beneficiary on two such occasions on Thursday and he capitalised on the reprieves to smash his eighth test century.

Neil Wagner, who had stepped in as nightwatchman on Thursday, set the tone when he tore into the South African attack after New Zealand resumed on 116-3.

Wagner clobbered two sixes and seven boundaries in his entertaining 49 before Kagiso Rabada removed him. Nicholls could not be denied his hundred though, a milestone the 30-year-old brought up with a square-driven four off Duanne Olivier (3-100). He fell in Olivier’s next over, edging him to second slip to depart after a fine knock studded with 11 boundaries.

Colin de Grandhomme made a quickfire 45 off 42 balls before New Zealand’s tail stung the tourists.
