Just recalled something from way back.
Entering AKL from SYD, after travelling down the coast a few weeks, we'd picked up a few souvenirs including a rather large coconut (plus husk, roughly rugby ball sized) my brother was taking home. As we were not particularly used to the quarantine process, we headed through the red lane and reported for inspection. Agent opens up bags and right on top is this massive coconut. Looks at my brother, almost surprised, and goes "Well you can't have THAT!". Brother picks up the coconut hands it right over and replies "Well here you go, then!". No further inspection and we were on the way, probably 20 minutes faster than the "nothing to declare" line.
The only lament was that we weren't aware of it a few weeks of carrying a large coconut around earlier.
