State Highway 21 (SH 21) is a short 6.7 kilometre stretch of highway in the North Island of New Zealand. It links State Highway 1, Waikato Expressway at Tamahere and State Highway 3 at Ohaupo. Its main destination is Hamilton Airport and Mystery Creek, where the National Agricultural Fieldays are held.

SH 21 was gazetted as a brand new state highway designation in 1997.^[1]

Oddities

State Highway 21 is actually 120 km south of where the number is supposed to be; in reality, it should lie somewhere in South Auckland. This southern placement makes SH 21 the second-most southern SH 2x highway, after SH 28.

At the exit to Hamilton Airport, State Highway 21 shows Hamilton to be in both directions (i.e. left to Hamilton and Rotorua, right to Hamilton and Waitomo Caves), and is possibly the only place in the State Highway network in which this happens. The actual difference between turning left and turning right is only 800 metres.
