The food contest has seen contestants from New Zealand competing in weekly food challenges to try to win the MasterChef New Zealand title and contract as a chef and recipe developer with My Food Bag.
Ms Bilton said she never imagined she would make it to the top six and had been equally excited to get into the top 16 contestants of the show.
"Then I worked my goal down, to 10 and now I am starting to get to the stage where maybe I could do this.
"I'm starting to believe in myself. I have always doubted it. I still get nervous cooking for others."
Ms Bilton said Richard Harris from Christchurch, who is "a bit of a dark horse", would be her biggest competition in the show.
In this week's competition she won dish of the day for her fennel-crusted venison loin with plum, red cabbage, broad bean salad and plum jam.
Ms Bilton said having to prepare and cook desserts was still the toughest thing in the contest.
"There is just so much science behind it.
"You've only got an hour and it could need an hour-and-a-half. I'm much more of a savoury girl. I don't even eat dessert so it's hard getting my head around that. I just hope we don't get one of those pressure-test dessert ones because I may as well walk away."
Ms Bilton said the biggest thing she had learnt from the show so far had been putting different flavours together and not being scared to do so.
"I've learnt to trust my own flavours and believe in myself ... If I don't want to be back in that bottom two I will need to bring out some of those big flavours to win."
What is up for grabs?
As well as the coveted MasterChef New Zealand title, the winner takes home a new Skoda Octavia RS wagon, a Belling Richmond range cooker and rangehood valued at $9000, a contract as a chef and recipe developer with My Food Bag and a year's worth of My Food Bag recipes and food deliveries, $2000 worth of kitchen products courtesy of Stevens Homewares and an exclusive cookbook deal with Allen and Unwin.
