In 2015, Nikki did not play in any strokeplay tournaments due to the birth of her first child, a son named Owen, in August. However, she did return to action to represent the Australian Ladies Professional Golf Tour (ALPG) in The Queens presented by Kowa, a matchplay tournament in Japan.
In 2014, Nikki made 19 starts and was amongst the most consistent performers, recording 9 top 10 finishes including 2nd at the ISPS HANDA Ladies European Masters and T2nd at the Deloitte Ladies Open.
In 2013, Nikki´s rookie season on the LET, she played in 20 events and added 3 top-10 finishes on the Ladies European Tour: tied for 5th at the ISPS Handa New Zealand Women’s Open, a tie for 7th at the Allianz Ladies Slovak Open Presented by Respect and 9th at the Sanya Ladies Open. She also posted a career low round of 63 (-9) with a bogey-free scorecard, during the first round of the Sanya Ladies Open. She ended the season ranked 31st and therefore, secured her rights to play in the 2014 season.
