Former National Party leader Don Brash joined The AM Show after saying he was "utterly sick" of the use of the Maori language in broadcasting.
Mr Brash criticises Radio New Zealand's Morning Report host Guyon Espiner's use of one of New Zealand's three official languages.
"When RNZ begins with a lengthy speech in Māori - several sentences, with no translation provided - there wouldn't be three percent of the country who actually understand Te Reo," he says.
"I don't want to be forced to listen to Guyon Espiner talk at some length in Te Reo without any explanation at all of what he's saying," he says.
"It's quite pointless. There's no translation provided. You can't learn anything from listening to it, you're just utterly bamboozled."
Mr Brash explains that he doesn't see why he should learn Maori to understand the radio programme.
"Why should I? Why should I?" he asks. "There are 20-odd radio stations which broadcast in Te Reo, and a Māori TV station."
"It is no value to me, essentially, at all," he says.
