Rival captains Brendon McCullum and Darren Sammy are taking a positive view of a new piece of technology to be used in the next two tests.
Real Time Snicko will be the latest tool in the third umpire's tool kit. The merging of picture and sound will take about 20 seconds and can be used to help identify edges, either for catches behind the wicket or lbws, upon a referral request from either side.
The system is being used in the Ashes series and it was quietly trialled at Dunedin during the first test.
The two captains and management teams met separately with match referee Roshan Mahanama, the International Cricket Council's general manager, Geoff Allardice, and ICC umpires' manager, Simon Taufel, before yesterday's announcement.
"It's fast, it's automatic and it's controlled by the technology providers, which is a bit different to the Snicko we've known for the last 10-20 years," Allardice said.
