Despite being full-moon-after period - traditionally a bad phase for snapper fishing - we've been enjoying good snapper fishing recently, both in the Rangitoto Channel and up in the Waitemata - particularly around the container terminal and naval base, with all popular methods working well (my young daughters did particularly well dragging light madai and slider type jigs tipped with squid strips and tentacles).
It pays to investigate any seabird activity right now. Most involve small to medium kahawai feeding on whitebait (some with snapper below), but occasionally you'll find medium-sized kings present instead. However, you may need to try and 'match the hatch' with smaller lures, as they seem focused on the tiny fish, completely ignoring the larger soft-baits and more usual stick-baits.
Northern Rangi' has been especially productive, but the good fishing could well extend further south, as we've only been trying north of the northern-most yellow buoy. We're finding 13-17 metre depths are holding plenty of snapper, including lots around 1-2kg, along with the occasional bigger specimen to 3.5kg. They're taking greeny-brown and brown coloured soft-baits in 3.5-5", with both casting and retrieving and dragging methods working.
