Most likely kahawai, which is quite a sporting fish, and puts up a good fight. I don't know about here, but in the Wairarapa my father used to catch red cod on a surf caster. Occassionally a nice snapper is caught both here and the Wairarapa as well. In NZ many people consider kahawai a rubbish fish, but I find it is great to eat if it is bled as soon as it is landed. Many different delicious ways to cook it too.
