The four-year deal runs until 2021 and designates Vodafone as a connectivity partner of NZR and an official sponsor of the national team.
The partnership will result in the launch of a new app centred on the national team. The app has been created in conjunction with pay-television broadcaster Sky New Zealand.
Fans will be able to use the technology to replay tries, view highlights and watch alternative live footage from multiple camera angles.
Vodafone will also provide broadband services in fan zones during the series.
New Zealand Rugby chief executive Steve Tew said: “We want to offer rugby fans the ultimate experience. This partnership with Vodafone means local rugby fans will have access to in-stadium technology that is at the forefront of what is available around the world to watch the game."
