"But I have to block it out and concentrate on my game and my game only. It will be quite hard backing up what I achieved in 2012 as it was a great year for me. It's a whole new year and I am going to try and start fresh."
Ko was always the easiest player on the course to spot at Pegasus last year. A massive gallery followed her every shot until the final putt. She faded in the final round from being the third round leader to finish in a share of 17th place.
After playing in major championships last year Ko is much more familiar with big crowds watching her.
"Before, I got really nervous playing in front of big crowds but I'm slowly getting used to it. The New Zealand Open is one of my most important tournaments and I'm always happy to play the Open."
The event has attracted a world-class field including three of the previous four champions.
Australian Lindsey Wright is unable to defend her title after withdrawing with injury.
Also in the field for the championship from February 8-10 at the Clearwater Golf Club are former major champions Anna Nordqvist and Sophie Gustafson (both of Sweden).
World No16 Angela Stanford and Cheyenne Woods, the niece of Tiger Woods, are other notable players in a field that will include 32 LPGA tour players. The all-star cast will also include European No1 Carlota Ciganda. It is the strongest field ever assembled for the NZ Women's Open.
Ko is excited by the prospect of becoming the first New Zealander to win the NZ Women's Open.
"It would mean a lot. It's making history within New Zealand and I would be so proud of myself."
The ISPS Handa NZ Women's Open is one of a few tournaments that Ko will play this in New Zealand. After her record-breaking season in 2012, she has two simple goals.
"I want to play as many LPGA tournaments as possible and also remain as the world No1 amateur."
