[17] Fekitoa featured off the bench in Munster's historic 28–14 win against a South Africa XV in Páirc Uí Chaoimh on 10 November 2022.

After completing his residency period, he was selected as a rookie in the New Zealand squad for the June 2014 test series against England, with coach Steve Hansen having signalled interest in him during the Super Rugby season.

His performance earned praise, with the Herald on Sunday saying that "the All Blacks coach has found the most elegant of solutions for Conrad Smith's back-up, one who carries more of an attacking threat than the veteran centre".

He was originally named as a reserve for the first test against Australia, however, with Conrad Smith and his wife expecting, Fekitoa was called up into the starting XV.

Fekitoa lost his starting spot to Anton Lienert-Brown, coming off the bench for the final Bledisloe Cup and the first Ireland fixture that year.

[33] Following the 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami, Fekitoa, whose family still lives in Tonga, set up a fundraising appeal to provide aid, raising in excess of £50,000.

[34] Wasps, Fekitoa's club at the time, supported his fundraising effort by donating 20% of the match ticket revenue from their fixture against Saracens on 30 January 2022.
