rndc -> wrong number of zones

[squid proxy]

I've bind9 installed under Lenny.

rndc status shows 35 zones, but I have only 21 zones in
/etc/bind/named.conf.local.

# rndc status
version: 9.5.1-P1
number of zones: 35
debug level: 0
xfers running: 1
xfers deferred: 0
soa queries in progress: 1
query logging is OFF
recursive clients: 0/0/1000
tcp clients: 0/100
server is up and running

in /etc/bind/named.conf I have just 5 default zones.
where else read rndc zones?

kind regards
Piotr
