I had some spare time today. So, decided to pull some statistical data from Chinese customs website (Home - GACC (customs.gov.cn)).

Here is data on import of IF into China from NZ for the last 18 months. Keep in mind it's not a2 specific but rather whole NZ import. I think it correlates quite closely with what @werdplaya58 provided above just shifted by one month which makes sense and I must say I do not see anything in this data that will make me worry. The interesting part is price per kg is very stable and in US$

Add here is data for NZ for the last 30 months separated by different customs regimes. I might be wrong, but I presume "Ordinary Trade" applies to products like a2 China label that sold in retail stores and "Customs Warehousing Trade" and "Entrepot Trade by Bonded Area" applies to CBEC trade but it's just my guess
