The Onslow Cricket Club commenced existence in time for the 1930-31 season, cricket in Khandallah having previously been played under the Khandallah Boys Club banner. The driving force behind the Club's development was Major F C Gentry and his three sons were prominent in the first years.

For the first few seasons only two teams were fielded, growth being hampered by the lack of a suitable home ground and the effects of the Depression. Once Nairnville Park became available for use in 1933-34 the Club started to expand and eight teams were fielded in 1938-39. Some players had difficulty with the 1.30pm starting time as Saturday morning work was common and transport less available than in modern times.

Nevertheless, the 1938-39 season saw five of the eight teams winning their grades. A standout performance was that of Ash Levastam who took 100 wickets in the season.

The forties were a difficult decade with the war taking its toll on playing numbers, although the Club revived sufficiently to progress to Senior grade status for the 1951-52 season. By this time Onslow was establishing itself as a strong club in the lower one day grades, a feature which has continued virtually unchanged in the half century since.

The one day teams domination of their grades was the basis of Onslow on several occasions winning the trophy awarded to the club with the most championship points across all grades, irrespective of the number of teams. To the fore in this were teams of players from the Onslow Rugby Club, throughout the decades a fruitful source of playing talent. This close relationship between the two Nairnville Park clubs was part of the tight community spirit of the district which carried over several generations.

As the New Zealand cricket team struggled in the late fifties, so did Onslow, with playing numbers dropping at adult and schoolboy levels. This was to end with Onslow losing Senior status in 1965-66. Things started to improve in the late sixties however and with class players such as Chris and Jeremy Coney in the top team, Senior status was regained for the 1970-71 season. Jeremy was to become Onslow's first New Zealand representative in 1973-74. Numbers of players grew, as did the strength of Onslow teams and in 1977-78 Onslow had a magic season. Pride of place went to the Senior team in winning the first Senior championship for Onslow. Two other grades were won and with other teams also showing strongly, the Club Championship was won for the first time in a number of years. Two years later, Onslow celebrated 50 years as a club and a large number of players achieved representative honours that year. 1979-80 started a decade which saw two other Senior titles and several other close chases for that honour.

Over the years Onslow has had a number of players play for Wellington at various levels and age groups. Of these, Jeremy Coney, John Morrison and Gavin Larsen have featured prominently for New Zealand, Jeremy becoming captain and Gavin playing over 100 one day International games for New Zealand.

After a brief appearance in the late forties, women's cricket returned to Onslow in 1978-79 and consolidated to the extent that Onslow dominated women's cricket in Wellington during the eighties and early nineties. Patricia McKelvey (long time New Zealand captain), Nancy Williams, Karen Musson and Maia Lewis (former New Zealand captain) have all represented New Zealand while playing for Onslow.

Junior cricket has in recent years thrived with the exposure of the sport on television. For a number of decades junior numbers were low and administration carried out by a few dedicated enthusiasts. As numbers increased dramatically in the early eighties, a separate club was established with parental administration better able to devote the necessary time to this important aspect of Onslow cricket. Junior cricket at Onslow has gone from strength to strength and the results are now feeding back into the senior club.

The nineties have seen mixed fortunes for a club that has finally seen itself as a genuine force in Wellington cricket at the top level. Onslow has continued to provide a number of representative players sometimes at a cost as representative commitments deny players the chance to perform for Onslow. With the amalgamation of the Wellington and Hutt Valley Senior competitions and a two tier Senior structure, Onslow has experienced mixed results finding itself in the second level for several seasons before winning its way back into the top grade for the 2002-03 season.

Onslow can look forward to the season and the future beyond with confidence.
