Irish all for South African powerhouses joining Pro14
Nucifora said the benefits of having them join what is at present the Pro14 would help develop Irish rugby and challenge the players.
Sanzaar was set up in 1996 to manage the Super Rugby club competition and the Test tournament now known as the Rugby Championship but Impey said it was now 'outdated'.
Victory for frontrunners the Bulls left them well placed to win the single-round competition which signalled the return of rugby to South Africa last month after a six-month break due to COVID-19.
The 28-year-old Springbok flanker limped off injured in a Super Rugby match against the Blues in Cape Town earlier this year and swift medical attention saved his leg from being amputated.
Steven Kitshoff and fellow Stormers front-row forward Scarra Ntubeni have gone into self-isolation after coming into contact with a person who tested positive for COVID-19.
It was the Stormers first match since rugby in South Africa was suspended due to the coronavirus pandemic.
It was the first competitive match in the land of the world champion Springboks since mid March when the Sharks beat the Stormers.
As the COVID-19 pandemic forces a rethink of how the Sanzaar flagship tournaments are conducted, New Zealand also said it would go it alone again with Super Rugby next year.
South Africa said it was seeking entry for four teams into Europe's PRO14 series, slamming New Zealand's 'unilateral decision' to pursue a domestic or trans-Tasman version of Super Rugby.
The competition went into lockdown with the rest of South Africa at the end of March but returns with three added teams and a chase to a unique finale in November.
The Bulls defeated the Sharks 49-28 and the Stormers overcame the Lions 34-21 behind closed doors in warm-up matches between the four Super Rugby teams from the republic.
Jordan Petaia, Lukhan Salakaia-Loto and Filipo Daugunu all scored tries in a bruising encounter to ensure the Reds made their first decider since winning the southern hemisphere Super 14 competition in 2011.
Reports claim Pollard's former side the Bulls, the Lions, the Sharks and the Stormers are set to replace the Cheetahs and the Southern Kings in the league which includes outfits from Ireland, Italy, Scotland and Wales.
The governing body oversaw Super Rugby's expansion from an initial 10 teams in 1995 to a peak of 18 in 2016, despite complaints from fans that the globe-crossing competition had lost its intensity and become too hard to follow.
Super Rugby sides the Bulls, Lions, Sharks and Stormers are set to tackle PRO14 outfit the Cheetahs, and domestic teams Pumas and Griquas in a local competition that SA Rugby had hoped would begin by the middle of next month.
The one point on which all agree is that the globe-spanning model which has seen teams regularly jetting from Buenos Aires to Bloemfontein is all but dead, with or without COVID-19 travel restrictions.
They led 32-16 after 55 minutes and then produced a gritty defence to hold off the desperate Highlanders who controlled the final quarter and threw everything at the visitors.
NZR said the planned revamp to the flagship southern hemisphere competition would contain New Zealand's five existing teams, one from the Pacific and two to four from Australia.
Hansen, who spent almost 16 years with the All Blacks said he felt that NZR should be doing what was best for their rugby players.
