keep their wider gauges, while narrow gauge railways were to be built. Member of the House of Representatives (MHR) James Crowe Richmond, who had worked on the Great Western Railway and in railways in Belgium, became the most prominent advocate for a uniform narrow gauge nationwide. In late 1869 Francis Dillon Bell MHR and Issac Featherston MHR (also superintendent of the Wellington Province) were in London to negotiate the retention of Imperial British forces then in New Zealand fighting the New Zealand Wars. They were also tasked with investigating a uniform railway gauge for New Zealand. In 1870, James Macandrew MHR called for another select committee to investigate the need for a law to require one uniform railway gauge for the entire colony. Information from Featherston and Dillon Bell reached Wellington in August 1870, and the second select committee to investigate whether a law was required for gauge uniformity met from that month. By majority the select committee reported back to the house in favour of narrow gauge being adopted as the uniform gauge nationwide, and allowing Canterbury Provincial Railways to continue to expand its broad-gauge network, with dual-gauge track where narrow gauge met broad gauge. William Sefton Moorhouse MHR, former superintendent of Canterbury Province and advocate for broad gauge, and William Rolleston MHR, at the time superintendent of Canterbury Province, were in the minority on the select committee opposing the legislation. Despite this opposition, Parliament passed the Railways Act 1870 in September 1870, requiring all railways to be built or converted to narrow gauge, with an exemption of the Christchurch-Rakaia section of Canterbury Provincial Railways. Sections of the Canterbury railway network were converted to dual-gauge, including Rakaia to Lyttleton, with new branch lines built to narrow gauge. By 1878, all of the broad gauge network had been converted to narrow gauge. Vogel Era From 1870, the central government of Sir Julius Vogel proposed infrastructure including a national railway network to be funded by overseas loans of £10 million, under the guise of the "Great Public Works Policy". Settlement and land sales to immigrants from Britain resulting from this infrastructure investment would pay for the scheme. The first narrow-gauge line was opened on 1 January 1873 in the Otago Province, the Port Chalmers Branch under the auspices of the Dunedin and Port Chalmers Railway Company Limited. Auckland's first railway, between Auckland and Onehunga, opened in December 1873. Vogel also arranged
