Piripiri had a cheese factory from at least 1910 to 1935. The local post office, called Matatera, opened in 1909, or 1910. Piripiri PO closed in 1913 and Matatera was renamed Piripiri in 1923. History 
The area was part of the Ngāti Raukawa rohe. In 1870 the Native Land Court designated the Piripiri block as , with a ban on sales. In 1887 the Court ruled that compensation for  taken by the Crown should be £67 19s, rather than the £25 to £45 per acre asked for by the owners. The ban on sales was removed in 1893 and in 1898 the Crown was allocated , 6 non-sellers being left with , which has now been sold. Piripiri had a population of 70 in 1901, 229 in 1911, 84 in 1951 and 89 in 1961. State Highway 2 
Contracts to clear a line,  wide, through the Seventy Mile bush, for a road, were let in 1871.  at the Piripiri Clearing was gravelled in 1881, though in 1882 the bush was still so dense that the trees kept the sun off the road, so it was felled in 1883. It was designated as a Main Highway in 1924, which later became SH2. Between October 2014 and September 2016 NZTA Central Region replaced a narrow bridge over the stream with a culvert and  of fill,  long,  wide and  high, on a reinforced concrete slab foundation and a Super-Cor Arch Culvert (corrugated iron and concrete), with  of rockfill on it, some  lower than the previous bridge. The previous 1927 bridge, which replaced a level crossing, was a  high viaduct,  wide between kerbs and  long, with a reinforced concrete deck. There had been a fatal crash at the level crossing in 1913. Railway station 
Piripiri had a railway station from 1896 to 1958. It was  chains south of Napier and  north of Palmerston North Central. A siding opened in 1894, a decade after the line was built. Its main purpose was to carry timber from the dense Seventy Mile bush, through which the railway had been cut. By 1879 the line to about  north of Piripiri had been surveyed, and from there, through Piripiri to Oringi, surveying of another  was being done. Although the line through Piripiri to Tahoraiti was reported as ready to open on 1 December 1884, it wasn't until 15 December 1884 that the  Matamau to Tahoraiti section opened, extending the line from Napier. The surrounding bush was leased in 1892, but an 1891 application for loading of firewood was refused, as it was said to be too close to Mangatera. Piripiri siding opened on 10 August 1894, but for use only by Rathbone & Mathews. In 1896 it had a loop for 4 wagons. From Monday, 1 June 1896 passenger trains called at the station, though no buildings were provided. From 15 August 1898 mixed trains stopped for parcels. By 1905 the station had a shelter shed with storeroom and cart approach to a platform and a passing loop for 35 wagons. A urinal was added in 1915. In 1966 Piripiri had a shelter very similar to the one which remains at Matamau. Also in 1894 Thomas Baker laid a tramway for Robert Holt's sawmill, which was milling kahikatea, matai, rimu and totara An 1898 fire burnt down their mill, but it had a 24-wagon siding in 1900, which was taken over by the Lands Department in 1908. It remained open for all to use until at least 1914. In 1900 Gamman built a new mill. A 1902 photo showed 22 workers at the mill. Gamman also had mills around the region at Ākitio, Bunnythorpe, Kumeroa, Manakau, Ohakune and Tahoraiti. From 1899 to 1909 Gamman's had a 15-wagon siding  north of the station. The government bought the land in 1903, the timber leases ended in 1909 and  were sold to farming settlers. The bush had largely gone by 1908 and the mills ran out of timber to fell after 1923. On 1 July 1938 Piripiri became a tablet switch-out station. On Sunday 16 November 1958 Piripiri closed to all traffic. A single track runs through the station site. Demographics

Piripiri Viaduct, over the Whakaruatapu Stream (a tributary of the Manawatū River), is  long and up to  high. It is now Bridge 146, a short distance east of Piripiri station. An 1882 contract gave the job of building Piripiri and Mangatera viaducts to M McKenzie of Dunedin for £9,350. It was built with totara. J & A Anderson & Co of Christchurch won a tender for a steel and concrete replacement. It was rebuilt in 1899-1900,  higher than the original bridge. The new Piri Piri Viaduct was tested under the weight of five locomotives in December 1900 and put to use on 31 January 1901. In the same era Andersons also rebuilt Kopua (1895), Makotuku (1898), Mangatera (1900), Ormondville (1906) and Makatote (1908) viaducts. There was a fire on the bridge on 29 October 1933. Underpinning with reinforced concrete beams was tendered for in 1969. References
