Holland and Hong Kong are the latest teams to qualify for next year's T20 World Cup in India.
The two nations join Scotland and Ireland in already qualifying for the 2016 T20 World Cup.
Holland beat Namibia by four wickets with just four balls to spare in Dublin to book their spot in the tournament, while Hong Kong narrowly defeated Afghanistan in the last over of the other play-off match to win a spot at next year's tournament.
The two losing sides still have one last chance to qualify, if they can win their remaining play-off match on Thursday, with Namibia taking on Oman and Afghanistan playing against Papua New Guinea.
Scotland will now play Hong Kong in the semi-finals and Ireland will play the Dutch in the other semi, with all four teams having already secured qualification by reaching the last four of the World T20 Qualifier.
