Hewitt was born in Christchurch and started competing in swimming competitions at the age of six.

Hewitt represented New Zealand in Surf Life Saving in 2001, but decided to switch to triathlon in 2005. In the same year she won gold at the ITU World U23 Championships.

The following year Hewitt won a bronze medal at her first Commonwealth Games in Melbourne. She finished her first triathlon season ranked ninth in the world and won the ITU International Triathlon Rookie of the Year award.

In 2007, she won gold at her first World Cup in Kitzbuhel, Austria, before placing eighth at her first Olympic Games in Beijing in 2008.

Since then, Hewitt has won multiple medals at World Championship level, placed sixth at the 2012 London Olympics, fourth at the 2014 Glasgow Commonwealth Games, and seventh at the 2016 Rio Olympics.

In 2017, she won the ITU World Triathlon in Abu Dhabi and the ITU World Triathlon on the Gold Coast.

Her coach and fiancé Laurent Vidal died suddenly in 2015 at the age of 31. In 2017, Hewitt set up a foundation in his name, the LV Foundation, to help up-and-coming athletes on their road to success.

Hewitt also has a degree in Economics from Canterbury University.
