I'm in the process of trying to complete my work visa application and looking for a bit of help from anyone who's been through it.
I've done ok so far but I've reached a section that want me to state the date I'll be arriving in and departing from NZ. Not sure how i

I'm not sure how I'm supposed to fill that in as I cant book flights until I have a visa (just in case) so dont know when I'll be arriving and I'm applying through Work to Residence so not actually planning to depart

Any thoughts anyone?
