NZ Post says delivering mail takes a backseat when it comes to workers safety.

Whangarei postie Wade Brock has been refusing to deliver mail to a Hikurangi address after a dog attack left him needing a tetanus shot last month.

NZ Post Spokesperson Marty Buckley says he agrees with Mr Brock's decision and measures have now been put in place.

Mr Buckley says as of today, a fence has been put up and mail delivery will resume.
