But with the 2018 schedule having taken on epic proportions with games to be played in Japan as well as London, Dublin and Rome, Sky have already confirmed they have the rights.
"We have a great line-up of All Blacks end of year rugby, and given the form of some of the northern hemisphere teams it should be a great spectacle for Kiwi fans," said Sky chief executive John Fellet.
"We have Eddie Jones' England hosting the All Blacks on November 10 at Twickenham. We have the Six Nations champions Ireland versus All Blacks the following weekend. And to wrap up the year, All Blacks versus Italy on November 24. We also have the special Japan-based Bledisloe match on October 27."
By tying up the last five matches of the year, Sky have ensured Spark and TVNZ won't be able to gain any production experience ahead of the World Cup next year. Neither have a recent track record of producing rugby coverage and the latter has come in for heavy criticism for its packaging and presentation of the Commonwealth Games on Australia's Gold Coast.
Viewers were left outraged at times at some of the editorial choices made by the directors and the heavy commercial intrusion which constantly interrupted events at key times.
