This year’s Lunar New Year will commence on 22nd January, with many factories closing for celebrations. Production will be impacted, and factories are busy trying to get the stock out before they shut down, in some cases for as long as two weeks. 
With this in mind, most carriers expect a low lifting in volumes and have planned to slide or blank sailings to Australia during the CNY period. 

There are no planned blank sailings for New Zealand tradelanes from China, though vessels are still being delayed due to terminal congestion in various ports across NZ.
A summary of BLANK / SLIDE plans for each service from China can be found here.
