In 1905 a progressive faction within the governing Liberal Party started to form in opposition to Liberal leader Richard Seddon's policies. They announced that they would stand in the election as the New Liberal Party, however an accusation against Seddon's son, when disproven saw most of the dissidents return to the Liberal Party, and of the three New Liberals (Francis Fisher, Harry Bedford and Tommy Taylor) that stood in the election only Fisher was returned.
