Blue cod are found from Stewart Island to The Three kings, but the biggest and best fish tend to be found in the southern parts of the South Island.
They grow to ~70cm and their fine delicate white flesh makes magnificent eating.
They prefer reef and low broken foul and will eat just about anything. As a result most baits are an option for catching these fish.
The best baits are any cut bait such as pilchard, skipjack, mullet, squid etc
Reefs and most areas of foul up to 120m.
