The 1931 Lower Hutt mayoral election was part of the New Zealand local elections held that same year. The elections were held for the role of Mayor of Lower Hutt plus other local government positions including the nine borough councillors, also elected biennially. The polling was conducted using the standard first-past-the-post electoral method.
A committee waited on the mayor, Sir Alex Roberts, requesting that he accept nomination for a second term as mayor. Roberts said he would consider the matter. He later said he would not accept nomination for another term.[1] His time as mayor had been dominated by the Great Depression where he did what he could to provide relief for impoverished. Former mayor Will Strand was asked to stand in place of Roberts, which he accepted to do.[2] The Lower Hutt branch of the Labour Party decided not to run a candidate for the mayoralty or a full ticket of council candidates.[3] With no other candidates emerging Strand was declared elected unopposed.[4] The Labour Party did nominate two council candidates.[5]
