Investigations are underway into each of the burglaries and it is not yet known whether they are linked.
Prevention manager senior sergeant John Fagan of the Whangarei/Kaipara Police said anyone with a firearms licence is required to store them securely.
"As well as the obvious concerns about unsecured firearms being stolen by criminals, if license holders fail to secure them they run the risk of having their licence revoked," he said.
"Living in a rural and remote area does not unfortunately make you immune to theft or burglary."
Police are also investigating the theft of six quad bikes from a rural property in Pouto over the long weekend.
They have asked for anyone with information on the burglaries to come forward.
