I'd still be keen to see the blog if you can re locate it.
I haven't really examined the port data that closely longitudinally (as the main analytic value is in comparing to previous months, and the most recent data is probably also not recent enough to properly capture any major disruption from lock downs).
However, looking at the March 2022 data, the vast majority of IF exports to China (all IF and not A2M specifically) are via seaport. About 95% of volume is via seaport and 5% is via airports in Christchurch or Auckland. The largest volumes are through Tauranga and Christchurch (Lyttleton) seaports (which were chopped off in my screenshot earlier).
