N'zonzi arrived at Ewood Park as a relative unknown after signing from French side Amiens in the summer.
The 20-year-old has forced himself into Sam Allardyce's plans and scored his first goal for the club in the 6-2 thumping at Arsenal last weekend.
N'zonzi is happy with his progress and is determined to keep his place in the starting XI.
"I didn't know (about playing regularly) when I came but it is good for me," N'zonzi told the club's official website.
"I hope I will continue to play, to progress every time."
