[3] Born in Dannevirke in the Manawatū-Whanganui region of New Zealand, Ronchi emigrated to Perth, Western Australia, with his family at an early age.

[5] Ronchi's first innings runs were critical in propping up New Zealand after a shaky start on an overcast morning in Leeds.

"[8] Ronchi is well known for his ability to score runs quickly and on 7 February 2007 he broke the record for the fastest domestic one-day hundred in Australian cricket.

Proving that he is in the Australian selectors minds for the future, Ronchi was chosen as Australia A wicketkeeper for their tour of Pakistan.

[10] In April 2008, Cricket Australia named Brad Haddin as the only wicketkeeper in its list of 25 contracted players, overlooking Ronchi.

[11] Despite failing to receive a contract, Ronchi was called up to the Australian team in June 2008 during their tour of the West Indies when Haddin was unable to play after breaking his finger.

In the final game of the series, he was elevated up the batting order to number three and batted very well to record the equal second fastest fifty by an Australian on his way to scoring 64 from 28 balls, including six sixes and was awarded the player of the match award (later in the same match David Hussey scored an even faster fifty relegating Ronchi's innings to equal third fastest).

[13] Ronchi made his debut on home soil in a Twenty20 match at the Melbourne Cricket Ground (MCG) against the South Africans as wicketkeeper when Haddin was rested from the team.

This was the highest by a batsman batting seventh or lower in ODIs, and also the third-highest score by a wicket-keeper, behind MS Dhoni's 183 not out and Adam Gilchrist's 172.

[22] Ronchi along with Grant Elliott set the highest ever record stand of 267 not out for the sixth wicket in ODI history.

[7] Following his international retirement, Ronchi signed for Leicestershire County Cricket Club to play in the 2017 NatWest t20 Blast.
