The striker is now tied to the Third Division club until 2015 after signing a two-year contract.
And Naismith's decision to sign on comes days after Fraser Aird and Chris Hegarty did likewise.
Naismith told the club website: "It's brilliant to be staying on at the club, and staying for two years is great as the gaffer is showing a bit of faith in me.
"Hopefully in that time I can get a chance in the team, take it and kick on, becoming a first-team member.
"I feel that I know what I want now and I know what I need to achieve to make it as a footballer.
"I'm ready to try to do that. I'm trying to be more professional about things so I'm training hard and trying to get in the team."
