National's agriculture spokesperson Todd Muller wants more balance in how the country's education system portrays farmers.
His comments come in response to a question in a Level 3 English paper that asked students to "discuss the way the writer explores ongoing change" in a New Zealand Geographic article.
The text quoted a survey showing two-thirds of respondents blamed farmers for deteriorating water quality.
Todd Muller says the piece painted a one-sided picture of New Zealand's farmers.
He speaks to Corin Dann.
