The Tonga prime minister, Lord Tu'ivakano, is expected to continue with his rebuttal of a motion of no confidence next Monday.
This comes after he has spent three days this week reading a letter defending his government's performance from opposition claims that it is unstable and had lost the trust of the people.
The Internal Affairs minister, Lord Vaea, says part of the reason for the lengthy defence are cultural difficulties centring on the Tongan translation of vote of no confidence.
He says this is ta'efalala'nga which means untrustworthy or unreliable and that is having an impact.
"The vote of no confidence and its meaningful direction in terms of the English translation and how that was actually put into the constitution, it hasn't come out well in Tongan and consequently the cultural aspect of it has some sort of different dimension to the actual English reasoning."
