The Highlanders have keep their Super Rugby playoff hopes alive and ended the Waratahs season a record 49-12 win in Invercargill.
Needing to score three or more tries than the Waratahs to secure a vital bonus point in the final round clash, the Highlanders stormed to a 42-7 lead at half-time and eased off after the break to conserve themselves for a next weeks quarter-finals.
The result was the home side's biggest winning margin against the Waratahs, who left five of their Wallabies players back in Sydney as part of a World Cup resting policy.
The Highlanders now face a nervous wait to see whether they have done enough, needing other results to go their way this weekend.
They now need the Lions to emerge with no competition points when they travel to the Bulls on Sunday morning.
A number of other scenarios could see the Highlanders scrape in despite a largely disappointing campaign of just six wins.
"We knew we needed to score tries and to get a good win to give ourselves any sort of chance," captain Luke Whitelock said.
"We've done our part. The guys were really focused on that and at times we played some really good footy.
"There's obviously a lot of different scenarios going on so yeah, it will be one of those tough weekends... Hopefully we can get one more week."
Josh McKay, Tevita Li, Thomas Franklin, Waisake Naholo and Teihorangi Walden each grabbed a try in the opening half, with the forwards setting up a penalty try in the 35th minute after destroying the Waratahs forwards at scrum-time.
Rob Thompson iced the win with a seventh try in the final minute as the Highlanders farewelled departing All Black fullback Ben Smith, who watched injured from the sidelines, in style.
Alex Newsome crossed for the Waratahs in the 28th minute and flyhalf Mack Mason had a late consolation try as the Sydney side bowed out with only six wins from a season overshadowed by the sacking of Wallabies fullback Israel Folau.
For All Blacks coach Steve Hansen, the performance of injury-prone Liam Squire may have been the most encouraging as the blindside flanker carried with strength and shredded the Waratahs defence in a rampaging first half.
