Hydroelectricity was a key driver of economic growth in the 1920s. Early in the decade Public Works Minister Gordon Coates set up a regulatory framework for electricity generation and reticulation, and initiated several major state hydro schemes. The power station at Mangahao in the Tararua Range near Shannon was opened by Prime Minister William Massey on 3 November. Construction had been hampered by the risk of sudden flooding and the difficult tunnelling required – seven workers were killed on the job. At the time Mangahao was New Zealand’s largest power station; today it is one of the smallest still operating.
Between September 1924 and February 1925 the All Black rugby team played 32 games in Britain, Ireland, France and Canada, including four test matches (against Ireland, England, Wales, and France). Scoring 838 points and conceding only 116, they won all their games, earning the nickname of the ‘Invincibles’. The 19–0 victory over Wales in Swansea on 29 November exacted some revenge for the controversial defeat suffered by the 1905 ‘Originals’. England was defeated 17–11, Ireland 6–0 and France 30–6. The touring team was captained by Cliff Porter, and included renowned players such as fullback George Nēpia, five-eighths Mark Nicholls and Bert Cooke, and forwards Cyril and Maurice Brownlie.
Māori spiritual leader Tahupōtiki Wiremu Rātana took a petition signed by more than 30,000 Māori to London. The petition called for the return of confiscated lands and for the Crown to honour promises made in the Treaty of Waitangi. Rātana hoped to meet King George V but was not allowed to. A member of his group also tried and failed to present the petition to the League of Nations in Geneva. But Rātana’s actions did help persuade the New Zealand government to set up a commission of inquiry into Māori land confiscations (the Sim Commission) in 1926.
The Night Limited Express between Auckland and Wellington, which was to become probably New Zealand’s most famous train, made its first run on the North Island main trunk line in December. The service was introduced at the urging of Railways Minister Gordon Coates, who sought to revitalise New Zealand Railways in the face of mounting motor competition. By limiting the number of stops and carriages, the train made the journey in 14¼ hours, instead of the 18 hours taken by the normal expresses. A Daylight Limited trialled in 1925–26 proved less popular and was later mainly confined to holiday periods. The Night Limited ran until 1971, when it was replaced by the all-sleeper Silver Star (1971–79) and the overnight Northerner (1971–2004).
