John Plumtree is the current forwards coach for the Hurricanes and is the former head coach of the Sharks, a rugby union team which competes in the Super Rugby and Currie Cup competitions. As a player Plumtree won two Currie Cup medals with the Sharks (1990, 1996); and as a coach he guided the Sharks to Currie Cup wins in 2008 and 2010. 
Plumtree was born on 16 July 1965 in Hawera, Taranaki. Plumtree and Lions coach John Mitchell were born and grew up in the same town, however, they only got to know one another later as players and coaches. Plumtree attended Hawera High School from 1976 to 1980.
Plumtree relocated to Durban, home of his South African wife. Reflecting on this move he later told the New Zealand Herald: "I did not want to get caught being a young rugby player in a small town for a long time. I thought if I got out of Hawera for a little while another door might open up." So he accepted the opportunity to play for Durban High School Old Boys RFC, home to quite a number of overseas players at the time. These included Murray Mexted, Mike Teague, Chris Butcher, Martin Whitcombe and Peter Winterbottom.
In 1988 Plumtree was selected by the then Sharks coach, Ian McIntosh. MacIntosh would later coach South Africa's national rugby union team, the Springboks. From 1988 to 1997 Plumtree played 80 matches for the Sharks, winning two Currie Cup medals (1990, 1996). In 1992, he briefly returned to New Zealand to play 14 games for Hawke's Bay.
According to the BBC, Plumtree was an assistant coach with the Crusaders Rugby Club in North Durban, helping them win "three successive Natal titles and the South African club championship in 1994-95".
After retiring as a player, Plumtree coached the Swansea Rugby Football Club in Wales for five seasons, winning the Welsh Cup (1999), the Welsh League (1998), and the Welsh-Scottish League (2001). He is credited with "discovering" Gavin Henson while he was with Swansea.
In 2001 he returned to New Zealand, briefly acting as video analyst for Mitchell, the All Black coach at the time, working in a team that included Robbie Deans, the New Zealander who coached the Australian national team until the series defeat by the 2013 British and Irish Lions. Video analysis was in its infancy, and Plumtree was frustrated by the buggy nature of the system. He later confessed that while he learned a lot from Mitchell and Deans, "video analysis wasn't my thing."
Plumtree returned to South Africa after he found that he was not to be given a New Zealand side in the Super Rugby tournament. Despite his success with Wellington, he was not appointed to guide the Wellington-based Hurricanes, as had been expected 
A spell as temporary head coach of the Sharks in 2007 was followed by a stint as assistant to Super 14 coach Dick Muir. Plumtree and Muir had been team mates at the Sharks during their playing days. Plumtree replaced assistant coach Theo Oosthuizen.
Under Plumtree the Sharks had again reached the top of the Currie Cup log by September 2009. In August 2009 the Sharks' coach received the Coach of the Month award from Currie Cup sponsors Absa.
The 2010 season was not off to a good start after a terrible Super 14 season for the Sharks however in the shadow of the abysmal performance, the 2010 Currie Cup season was highly successful for Plumtree as the Sharks won the 2010 ABSA Currie Cup.
- These data are mostly from the Sharks' website, which conflicts to some degree with information available elsewhere. Swansea RFU's website records that Plumtree played 15 games for Hawke's Bay. The International Rugby Academy lists 90 games for the Sharks, and different starting dates: 1986 for Taranaki, and 1989 for Natal.
