A constituency report from Ha'apai stated cartons of chicken were selling for as much as 27 US dollars.
Radio Tonga reports Tongatapu MP Mateni Tapueluelu questioned who should take the blame for the prices.
The Minister of Revenue Tevita Lavemaau says the price of chicken is controlled by the government's Competent Authority.
Mr Lavemaau says the only tax imposed on chicken is 40 seniti or 18 US cents per kilo so such goods should not be expensive.
