Fans will need a subscription to both Spark Sport and Sky Sport to watch all three Black Caps tests in June.
Sky TV has announced that it will broadcast the World Test Championship between the Black Caps and India, while Spark Sport will broadcast New Zealand's two tests against England on June 2 and 10.
Spark Sport last year won the rights to broadcast New Zealand Cricket for six years.
The deal meant Spark Sport snagged the rights to NZ Cricket games played in New Zealand (including the Black Caps and White Ferns), while Sky still has the rights to Cricket Australia games played in Australia and BCCI (India) games played in India and the IPL, as well as other international and domestic matches.
Spark Sport also has the rights for international and domestic cricket matches played in England, under the England and Wales Cricket Board (ECB), in a four-year deal announced last year.
