Te reo Maori has been an official language since 1985 and Parliament has translators to translate for both MPs and audiences of Parliament TV. However, Mr Peters argued that left out broadcasts on radio.
Mr Flavell later hit out at Mr Peters for "anti-Maori rhetoric" following on from his call to abolish the Maori seats.
"Every chance he gets he puts the boot in. To accuse me of hiding behind my native tongue harks back to an age when Maori were actively discouraged from speaking te reo.
"I thought we were living in the 21st century - not the 19th century," Mr Flavell said.
Mr Tabuteau told the Rotorua Daily Post Mr Peters had been instrumental in the past in getting funding for kohanga reo and the national kapa haka competition.
"It was a quip at our [parliamentary] process. These are important matters for discussion and there is no translation on radio or television, or even in the [press] gallery."
