[14] As Hekari Souths United, the club were favoured to retain their title in the 2007–08 season, having obtained the services of Solomon Island internationals Abraham Iniga and Jack Samani.

[18] The club then finished top of the NSL regular season table too, and won the Grand Final 3–2 against Gelle Hills, with all three goals coming from Kema Jack.

The team finished top of the regular season table, but the Grand Final, set to be played against Rapatona FC, was postponed twice before being cancelled entirely, with the title being awarded to Hekari by virtue of a higher league position.

[19] In October 2009, the club began to take part in the 2009–10 OFC Champions League, changing their name simply to Hekari United, and entering Group B alongside Lautoka of Fiji, Tafea from Vanuatu and Marist from the Solomon Islands.

In the two-legged final, Hekari faced two-time winners Waitakere United, and the first leg in Port Moresby saw the Papua New Guinea side win 3–0, with goals coming from Kema Jack (2) and Solomon Islander Alick Maemae.

[21] Meanwhile, the side won their fourth straight domestic title, topping the regular season table during the 2009–10 National Soccer League and defeating Gigira Laitepo Morobe FC 5–0 in the Grand Final on 24 April 2010.

[22] Ahead of the Club World Cup in December 2010, the side recruited Fijian international Osea Vakatalesau and veteran Solomon Islands striker Henry Fa'arodo to bolster their prospects at the competition.

[26][27] They once again represented Oceania at the 2011–12 OFC Champions League, and provided a much sterner test, once again facing Amicale and Koloale and finishing ahead of both sides in the group, but were eliminated on 3 March 2012 after a late goal from Auckland City's Alex Feneridis salvaged a draw for their New Zealand opponents.

[28][29] On 15 April 2012, the side won their sixth league title with a 3–0 victory over Eastern Stars, with goals from Taniela Waqa, Kema Jack and Wira Wama.

Despite the OFC format change allowing both the group winners and the runners-up to progress to the knockout-stages, Hekari were unable to capitalise, winning just one game and finishing with 4 points.

[39][40] They returned to domestic action and topped the regular season table, and were drawn to face Madang FC in the Championship Playoff Semi-Finals on 16 May 2015.

For the first time, two clubs from Papua New Guinea were invited to the competition, with Lae City Dwellers joining United as winners of the Grand Final.

[44] In the OFC Champions League, Hekari scored big wins against AS Lössi of New Caledonia (5–1) and Suva of Fiji (3–0), but were unable to overcome New Zealanders Team Wellington for the second consecutive season, going down 4–0 and being eliminated from the competition at the group stage.

[8] In the 2018 edition of the National Premier League, Hekari were drawn in the Southern Conference but were unable to top the group, finishing second and, as a result, failing to qualify for the final.

[52] Following the dissolution of the FFPNG in October 2018 and the merging into the PNGFA, chairman John Kapi Natto declared that Hekari will 'obviously' make a comeback ahead of the 2019 season.

[57] They faced fellow conference rivals Eastern Stars in a two-legged semi-final, which they came through 4–1 on aggregate, setting up a final against reigning four-time champions Toti City.
