Root shines before New Zealand collapse in second Test

An unbeaten Joe Root century and a bowling masterclass by James Anderson have put England in complete control of the second Test, as New Zealand's hopes of levelling the series plunged with shambolic batting on a rain-hit day two.

The Kiwis were 7-138 when showers fell midway through Saturday's final session at Basin Reserve and forced play to be halted for the day, still 297 runs short of England's declared first innings total of 8-435.

Though Harry Brook (186) was denied a double-century in a 302-run stand with Root, the former England skipper marched on to an unbeaten 153.

Ben Stokes' declaration paid immediate dividends as Anderson, the world's top-ranked test bowler at the age of 40, scythed through New Zealand's top order with three quick wickets.

Spinner Jack Leach grabbed another three and Stuart Broad one, leaving wicketkeeper Tom Blundell (25no) and tail-ender captain Tim Southee (23no) facing an improbable rescue mission.

"It was a brilliant call," Root said of Stokes' declaration. "We might not be sat here with them seven down tonight, so credit to him."

New Zealand were thrashed by 267 runs in the series-opener in Mount Maunganui, and have plumbed new depths in the nation's capital.

Their bowlers were humiliated by Brook and Root on day one, while their batters crumbled meekly on day two.

"It's been disappointing," New Zealand batting coach Luke Ronchi said.

"Guys are sort of struggling with ... the trust element of things.

"But that's the message that we're going to keep giving them - to trust their skills."

Opener Tom Latham (35) and No.5 Henry Nicholls (30) made starts but both fell trying to reverse-sweep Leach, before Daryl Mitchell was out for 13 off Leach's last ball before tea.

Ollie Pope took a brilliant, one-handed catch at silly point to remove the all-rounder but Mitchell was culpable for hitting in the air off the face of the bat.

It was Pope's second one-hander, having taken the first with his left after a sweeping Nicholls top-edged into his own elbow, with the ball pinging over his shoulder to the fielder.

All-rounder Michael Bracewell later spooned a catch straight back to Broad to be out for six.

Only opener Devon Conway (0) and number four Will Young (2) might feel at peace with their dismissals, both beaten by good balls from Anderson that caught thin edges on the way to wicketkeeper Ben Foakes.

England's batters also threw away wickets on day one but it was of no consequence due to Root and Brook's contributions.

With rain forecast on day three, the weather could yet thwart England's hopes of sweeping New Zealand.

However, a draw will be enough to complete their first series win in the nation since 2008.
