When activity in the fledgling Republican Party petered out, Jesson wound up the party in 1974, but continued to publish a widely read pro-republican broadsheet entitled "The Republican" (1974–1995), covering both republican and leftwing issues in a plain and unpretentious style. This journal also featured articles by many other New Zealand leftists. ("The Republican" merged into Chris Trotter's "New Zealand Political Review" in 1995). Jesson was a founding member of the Republican Movement of Aotearoa New Zealand, until his death in 1999.
