South Africa has New Zealand's support to host the 2023 Rugby World Cup.
World Rugby announced this week South Africa came through a vigorous process to emerge ahead of France and Ireland as preferred hosts.
South Africa scored 78.97 per cent; France 75.88 and Ireland 72.25 over a range of criteria from World Rugby's technical review board.
The decision is not binding, with intense lobbying to now begin and votes still to be cast on November 15, but New Zealand Rugby chief executive Steve Tew has revealed his three votes will go the way of the Sanzaar partner.
"From a New Zealand point of view, our board made a decision early on that if the process was seen to have worked well and been done fairly and professionally then it would be very hard not to vote the way of the recommendation," Tew told the Weekend Herald in London.
