A statement from Spark said the coverage would begin on Wednesday with coverage of the England-West Indies Test series with the start set for 10pm New Zealand time (8pm AEDT).
This series has been christened #raisethebat series and involves three Tests in three weeks; it will pay tribute to key personnel who have helped during the COVID-19 pandemic.
Other tournaments to be covered under the deal are those played under the ECB banner, including all men's and women's home internationals, the County Championship, the Vitality Blast, the Royal London Cup and The Hundred which has attracted a big audience from the cricketing world.
"England has a rich cricket history and the fan base is engaged from grassroots right through to the professional level so it's great to know that Spark Sport will play a pivotal role in growing the game as a key delivery partner in New Zealand," he said.
"England's staunch New Zealand fan base can look forward to scheduled future international events of the deal, including India's five-Test Tour in 2021 and a bumper 2022 summer with Test tours by South Africa and New Zealand. This will be the Black Caps first Test series in England since 2015."
ECB chief commercial officer Tony Singh said: "This is a great partnership for cricket fans in New Zealand, and we hope viewers will enjoy watching the first international Test cricket to be played since the COVID-19 outbreak with next week's #raisethebat series between England and the West Indies.
"This deal means fans will also be able to see some of the world's biggest stars and coaches in the unmissable first season of The Hundred, our action-packed new 100-ball cricket competition which launches next year, and New Zealand's tour of England in 2022.
"We're excited to be working with Spark Sport as it pioneers a fresh approach to sports delivery in New Zealand."
