Rangiriri is a locality in the Waikato region of New Zealand.
Rangiriri was the site of a major Māori defence structure during the time of the Invasion of the Waikato, the major campaign of the New Zealand Wars. The Battle of Rangiriri, which took place on 20–21 November 1863, cost both sides more than any other engagement of the land wars and also resulted in the capture of 183 Māori prisoners, which impacted on their subsequent ability to oppose the far bigger British force.
To replace a punt, which had been operating since at least 1900, a timber truss bridge, with ferro-concrete piles, was started in 1915 and probably opened in 1917. It partly collapsed, but was strengthened to allow light traffic. Demolition of the old bridge cost $30,000.
About 1969 a single-lane replacement, designed by Murray-North Partners, was built downstream for £204,800 (National Roads Board £182,300, Raglan County Council £15,525, Waikato County Council £6975). It is 900 ft (270 m) long, with 8 spans, 6 of 120 ft (37 m). The 2-cell H-section box girder is formed of 3 prestressed, post-tensioned segmented concrete flanged beams. The design was the first in this country to combine precast units into a continuous box girder.
