Kelvin Grove itself is a relatively new suburb, with housing beginning in the 1960s. The suburb itself is mostly rural, however there is a sizeable growth in development in the area which should soon see the suburb becoming more residential.
Kelvin Grove has three schools. They are Cornerstone Christian School, Te Kura Kaupapa o Manawatu and Westmount School. However, it is more likely children from Kelvin Grove would attend the nearby Roslyn and Freyberg High Schools. There is also a kindergarten here.
The area was also home to fuel depots.
Peppertree Rest Home is located on Roberts Line.
At the 2001 Census of Population and Dwellings: Kelvin Grove had a population of 3,240. 
The original inhabitants of the area were the local Rangitāne iwi, and was part of the Te-Ahu- a-Turanga Block which was sold by Rangitāne in 1865.
The first Europeans arrived in Kelvin Grove in 1871 when Scandinavian immigrants settled in the area around present day Roberts Line-James Line and Napier Road block. This area and also that of Whakarongo, became known as the Stoney Creek Scandinavian Block. At this time the area was mainly thick forest, which had to be felled in order for settlement. This was achieved by the mid-1870s.
In 1893, Kelvin Grove School was established and Kelvin Grove as an entity of its own was established. Kelvin Grove was the name of the local sawmill (which had opened in 1879). In 1901, Kelvin Grove Hall was built. In 1921, however, the Hall burnt down and was not replaced until 1935.
In 1939, Kelvin Grove School closed down, due to parents choosing other schools such as Milson or Terrace End.
In 1950, part of Kelvin Grove was brought under the jurisdiction of Palmerston North City, but it was not until 1966 when houses began to appear especially in the Karamea Crescent and Mahia Place area. 
Kelvin Grove's street name themes vary from those of New Zealand place names (Kaimanawa, Anakiwa, Karamea, Mahia, Wairau) plants (Acacia) or even those of past Councillors (Mihaere).Kaimanawa Park
