Enari was part of the 2016 and 2017 New Zealand Under-20 sides and had success when they won the Junior World Championships in 2017. However, he has had a career frustrated by injuries before becoming a key member of the resurgent Hawke's Bay team in Bunnings NPC rugby this year.
He played 40 times for Canterbury between 2016-20, and played nine games for the Crusaders in 2017.
He took to social media to thank the Crusaders and Canterbury for all they had given him and said he was looking forward to the new challenge.
He will have the chance to form a combination with Wallabies five-eighths Christian Leali'ifano, whose signing was announced at the weekend.
Also announced in the latest batch of signings is Auckland lock/loose forward utility Sione Tu'ipulotu and loose forward Solomone Funaki, who also plays for Hawke's Bay.
Tu'ipulotu made his first-class debut for Manawatu, playing 11 games in 2019 and six games for Auckland in 2020. He played for Tonga Under-20 in 2015 and Samoa Under-20 in 2016.
Funaki has played for Hawke's Bay since 2018 and was in the Highlanders in 2020-21.
Both made their Test debuts for Tonga in their Mt Smart Test against the All Blacks in July.
Three Samoan players, Neria Fomai, Tomasi Alosio and Henry Taefu, were also named.
Fomai and Alosio played for Samoa in the July Tests this year after earlier playing on the World Sevens circuit.
Fomai, 29, educated at Hastings Boys' High School, plays on the wing for Hawke's Bay. He played eight games for Southland in 2017 but has played 25 times for Hawke's Bay since 2019. He appeared in 15 tournaments for Samoa on the World Sevens circuit between 2013-18.
Alosio, 29, plays club rugby for the Hutt Old Boys Marist side in Wellington. He made his New Zealand provincial debut in 2015 while on the World Sevens circuit he has appeared 201 times for Samoa.
Taefu, 28, a centre, has played 27 games for the Force since 27. He played four games for the Reds in 2016 and then had 20 games for Colomiers in 2017-18. He has played nine Tests for Samoa and was an Australian Under-20 international in 2013.
On Tuesday, Moana Pasifika also unveiled 110 cap Wallabies prop Sekope Kepu as their latest signing and will continue to name players at 2pm each day on their social media channels.
