"It was great getting to the finals for a second time. I had no expectation to win and definitely didn't think it was going to be me. It's a tough competition with awesome competitors and it was harder than last year.
"If I was to say anything to other electrical apprentices in New Zealand, I'd say 'Just do it, and get involved with the Challenge. You've got nothing to lose and everything to gain in terms of a great experience."
Ms Court applied for an apprenticeship with etco after hearing about it on the radio.
"I absolutely love it. I'm doing something different every day, meeting new people and constantly learning new skills. One day I hope to have my own electrical business."
Master Electricians operations manager Bernie McLaughlin said it had been a nail-biting finish with a very high level of achievement but Ms Court had remained focused.
"She is a very determined individual. She'd left no stone unturned in terms of her preparation. She was totally focused, from the preliminary regional rounds right through to the final, and she hit the ground running."
The finalists faced five rounds of two-hour-long modules, completed over three days of competition, interspersed with off-site challenging activities and team bonding.
Mr McLaughlin said the number of entries to this year's Challenge had rocketed, with employers and trainers using preparation for the contest as part of their training programmes - making it tougher than ever to reach the final.
Champions can go on to enjoy international opportunities, with the titles opening doors for them to represent New Zealand at WorldSkills Competition events.
