"There is a certain point where you can get to here but after that to improve you have to see what is going on overseas and get competition."
The 26-year-old says there is no reason why another Kiwi player cannot make the top 100 but the cost is a big factor.
"One of the major things is obviously funding and sponsorship to get these youngsters to go and play overseas, and not many people - if any - can afford it. Tennis in New Zealand isn't the top sport and that is a shame but that's the way it is. It is tough but I think there is still a chance to produce players."
Erakovic enjoyed catching up again with Peter Blow, who once coached her.
"I do remember him taking us on a trip to Brisbane; I think it was the under-14s. Peter is a great guy, very funny and very creative, especially with youngsters. There was a lot of enjoyment when he took us on his trips."
Erakovic said she loves interacting with young tennis players at coaching clinics like yesterday at Mount Maunganui.
"I really enjoy interacting with the youngsters and really enjoy what is going on. I look at myself when I was a kid and Brett Steven came, or one year Michael Chang came from the States.
"It is super exciting and it actually made me want to play more tennis - so it was a good thing," she said.
