Danny Holla was the hero as VVV-Venlo retained their Eredivisie status, while Willem II secured promotion to the top flight.
Willem II beat second division rivals FC Den Bosch 2-1 in the second leg of their play-off having earned a goalless draw from Thursday's first leg at the Stadion De Vliert.
The hosts completed the job thanks to goals from Marc Hocher and Jens Podevijn to claim their spot back in the top flight, having been relegated in 2011.
Den Bosch, who were reduced to 10 men midway through the second half when Ralf Seuntjens was sent off, pulled a goal back right at the end through Bart van Brakel's free-kick but they did not have enough time left to find an equaliser.
VVV-Venlo will also be playing top-flight football again next term following a hard-fought 2-2 draw in the second leg of their play-off against Helmond Sport.
Holla scored the winner in the first leg on Thursday and he scored a brace on Sunday afternoon, including a second-half penalty to help the hosts retain their place in the top flight against a Helmond side who were hoping to earn promotion.
Holla broke the deadlock before strikes from Sebastian Stachnik and Zarko Grabovac gave the visitors a 2-1 lead and levelled the tie after just 14 minutes.
But Holla's spot-kick midway through the second half handed VVV the initiative again and they held on to the relief of the home fans.
