  Mercer is a village in the Waikato District Council area of the Waikato region of the North Island of New Zealand. It is 70 km north of Hamilton and 58 km south of Auckland, on the east bank of the Waikato River, 2 km south of its confluence with the Mangatāwhiri River.
  
  Prior to the creation of the Auckland supercity in 2010, Mercer was in Franklin District, part of the Auckland Region.
  
  ## History
  
  The first attack in the invasion of the Waikato took place on 17 July 1863, when about 15 Māori defenders were killed at Koheroa (a kilometre north – see 1:50,000 map). The village was named after Captain Henry Mercer, who was killed at Rangiriri in November 1863. The navy river gun-boat Pioneer was wrecked on the Manukau bar in 1866 and one of the gun turrets forms part of the war memorial.
  
  The North Island Main Trunk railway opened to Mercer station on 20 May 1875. A crash in 1940 killed the driver and fireman. Until 1958 many trains stopped for refreshments. The station closed in 1986.
  
  The beached hulls of steamers operated until 1976 by Caesar Roose can be seen on the west bank of the river just south of Mercer. W. Stevenson & Sons Ltd bought the remains of the Roose sand dredging business in the mid 1980s and, after dredging ended in 1997, redeveloped 2.5 ha (6.2 acres) of its yard with a petrol station and a food court.
  
  ### Bridge
  
  In 1965 Roose offered $100,000 towards the $343,000 bridge to replace the Mercer ferry. The 480 ft (150 m) long single span concrete Caesar Roose Bridge was opened on 18 November 1972 by Roose's daughter, Jeanette Thomas, with the Minister of Works, Percy Allen.
