The road followed the route of a Māori track which was not suitable for wheeled vehicles. In the early 1840s "it was usually easier to pile up the timber and burn it" than to transport logs out; at Boxhill in Khandallah the atrocious road condition could require eight or ten bullocks to pull carts through.
William Mein Smith and the
New Zealand Company cleared bush alongside the track and widened it in 1841, allowing the sale of sections along it from June. In February 1843 the company widened it to and cleared bush to either side. Labourers got 14 shillings a week, and skilled carpenters and bricklayers £4; accommodation was not provided and most used tents. Settlement stopped at The Halfway (now
Glenside) north of Johnsonville because the
Ngāti Toa under
Te Rauparaha and his nephew
Te Rangihaeata questioned Colonel
Wakefield’s land purchases in the Porirua Basin. They destroyed bridges, felled trees on the track and posted warning notices. In late 1845 the government reinforced the two companies of soldiers in Wellington with six hundred more troops. A show of force in the Hutt Valley ended with Ngāti Toa given £2000 (in instalments) for the disputed land at Porirua. After the "Maori scare" of 1845-46 Governor Grey had the road from Jackson's Ferry or Fort Elliott in Porirua and The Barracks at Paremata to Wellington upgraded to wide by soldiers of the 58th and 99th Regiments under Captain
Andrew Russell, assisted by Maori labourers. They were paid 2s (shillings) or 2s 6d per day; or 2s for the chief in charge and 1s for labourers. This employment was "very popular". The road from Jackson's Ferry at the south head of
Porirua Harbour to the Hawtrey Church was seven miles and four chains (11.3 km) long and cost little more than £700 per mile. The upgrading opened in December 1847 but was not completed until the end of 1848, well after any hostilities. Tyrone Power an Army officer said that in 1846 the road was
a forest path, so bad and unpractical that all supplies had to be sent around by sea (to the Army at Porirua) but he wrote in 1847 that
The road that used to be so bad and dangerous is now nearly a pleasant ride, and in the course of a month will be open all the way through for carriages and carts. Bishop Selwyn wrote in 1848:
What an agreeable change from former journeys through the deep mud and fallen trees and the totara flats. A road perfectly smooth and almost level enabled me to proceed as comfortably by moonlight as in broad daylight == Military Stockades ==
