Tangata Whenua was a groundbreaking six-part documentary series that screened (remarkably in primetime) in 1974. Each episode chronicled a different iwi and included interviews by historian Michael King with kaumātua. These remain a priceless historical record. The Feltex Award-winning script was by King and director Barry Barclay. The NZBC said the series had "possibly done more towards helping the European understand the Māori people, their traditions and way of life, than anything else previously shown on television".

The Governor was a television epic that examined the life of Governor George Grey in six thematic parts. Grey's "Good Governor" persona was undercut with laudanum, lechery and land confiscation. NZ TV's first (and only) historical blockbuster was hugely controversial, provoking a parliamentary inquiry and "test match sized" audiences. It won a 1978 Feltex Award for Best Drama. Auckland Star reviewer Barry Shaw trumpeted: "It has made Māori matter. If Pākehā now have a better understanding of the Māori point of view [...] it stems from The Governor.
