Pivac will take over at Wales in July after coaching Welsh club Scarlets for a final season.
Wayne Pivac will take over as Wales coach when Warren Gatland steps down after next year's Rugby World Cup, the Welsh Rugby Union has announced.
The appointment of Gatland's fellow New Zealander Pivac, the current Scarlets boss, is the end of a two-year recruitment process undertaken by WRU chief executive Martyn Phillips and chairman Gareth Davies.
"I've been in New Zealand and I just flew in yesterday".
"For me it was a matter of how I would fit in with Wales and I've really enjoyed the experience, both in and outside the rugby environment in Wales". Gatland is set to walk away from his role as Wales boss following the 2019 Rugby World Cup and will be replaced by a fellow Kiwi.
In the wake of that trip, Pivac turned the Scarlets from also-rans into a genuine force both at home and overseas.
Fellow Kiwis Dave Rennie, the Glasgow coach, and Scott Robinson were also short-listed for the post, but Pivac also ticked the worldwide rugby box having coached Fiji between 2004 and 2007.
Pivac meanwhile led the Scarlets to the Guinness PRO14 title in 2017 for the first time in over a decade, before again taking them to the final this season where they lost to Leinster, along with a European Champions Cup semi-final.
"I had a taste of worldwide rugby with Fiji and thoroughly enjoyed that. I will be talking to Warren obviously in the coming days and weeks and making sure we continue to work together for the benefit of Welsh rugby", Pivac said.
"I think the Union's in good hands and I want to be part of it".
The former policeman will have a watching brief at the 2019 World Cup that autumn before Gatland's 12-year reign comes to an end.
"I can pick the phone up any time to Warren to talk about a player and he can do the same as well".
"Nothing will change over my role at the Scarlets in the next 12 months".
