I sure hope not. Flying to the US for a week on Thursday.
How essential is your travel? Are you in an at risk group?
Number of total confirmed COVID 19 cases by date compared between USA and Italy 11 days prior.
The chart is two days old, but it is Friday the 13th in the USA and confirmed cases are 2,030 now:
There is widespread concern of massive under-testing in the USA, a state of emergency has been declared.
As others have said, the USA is unlikely to travel ban us in the next week, and assuming you have a NZ passport, you will be let back into NZ. You may have to do self isolation on your return.
If NZ issues a travel warning against the USA this weekend it may impact your insurance. Possibly a bunch of flight cancellations will be announced if NZ puts in place travel restrictions from the USA this weekend, but there probiably will be enough flights to get you home in under two weeks time.
If you are in an at risk group or don't have a NZ passport, I would not be leaving the country at the moment.
