Lions vs Waratahs will play South African conference winners the Lions in their Super Rugby semifinal in Johannesburg next weekend.
The Tahs earned a last four spot on Saturday with a 30-23 home win over the Highlanders in Sydney, where they scored 24 unanswered points to overturn a 23-6 halftime deficit.
The Lions scored a 40-23 win over Argentina’s Jaguares (Jaguares) at Ellis Park on Saturday (Sunday morning NZ time) to secure home advantage for the semifinal
Losing finalists for the last two years, the Lions beat the Waratahs 29-0 in Sydney back in April.
The other semifinal will be an all-New Zealand contest between the defending champion Crusaders and the Hurricanes, in Christchurch.
Back in Johannesburg, and Springboks first-five Elton Jantjes kicked 20 points as the Lions outpointed the Argentinians in the quarterfinals.
The Jaguares opened with two Nicolas Sanchez penalties for a 6-0 lead before the Lions raced out to 24-6 after tries to Ruan Combrinck, Harold Vorster and Boks hooker Malcolm Marx.
Batuista Delguy and Pablo Matera scored tries for the visitors early in the second half with Delguy rounding off a superb team effort, but a try to fullback Andries Coetzee and good goalkicking from Jantjes closed it out for the Lions.
