Sky TV topped off another busy week for local sport broadcast rights by securing rights to broadcast all SANZAAR matches until 2025.

The agreement will see New Zealand Rugby take a five percent stake in Sky.

Sky's deal is comprehensive. It includes all coverage of the Investec Rugby Championship, Steinlager Series, Investec Super Rugby and Mitre 10 Cup. It also covers all other domestic Rugby including women's competitions.

Neither side put a price on the deal, details are confidential, but media speculation came up with figures of well over $200 million. In effect the value of the agreement is greater than half of Sky TV's market capitalisation. It is also far higher than the cost of previous Rugby rights in this country.

The move saw Sky's share price get an immediate boost of around 24 percent after falling a week earlier when Spark Sport picked up the rights to domestic cricket coverage. The share price is still down on the year by around 40 percent.

Sky will show games on its satellite TV service as well as its online streaming services. Some matches will play free-to-air on the Prime channel.

The deal was confirmed by shareholders voting at Sky's annual general meeting on Thursday.

Sky also cut a deal with the New Zealand Open golf tournament this week.
