The Lions will have a home advantage as they chase their first Super Rugby crown against the Crusaders which are seven‑time champions in the competition.
The Lions stormed back from 22‑3 down late in the first half to claim a 44‑29 win over the Hurricanes to keep the final in Johannesburg this weekend.
The Crusaders who finished second behind the Lions in the regular season standings will have to make the trip to South Africa after beating the Chiefs 27‑13 in the other semi‑final in Christchurch.
It will be the fourth time a Super Rugby final has been staged in South Africa since 1996.
The Lions will be aiming to give their coach Johan Ackermann a fitting send‑off after four years in charge.
Crusaders coach Robertson is optimistic No 8 Kieran Read and tighthead prop Owen Franks can play the final against the Lions in Johannesburg.
The two All Blacks were replaced during the 27‑13 semifinal win over the Chiefs because of injury concerns.
