How many mobile phones one can bring in?

Is there any limit on the number of mobile phones, a person can bring in to NZ?

I have 3 mobile phones which all have SIM card(s) from different countries. I would like to know, whether i can bring in 3 mobiles to NZ or will there be any issues at the customs during entry?

You can bring the phones without problem, but can be told to unlock any device(s) for the border authorities to inspect the contents. https://www.stuff.co.nz/travel/news/...secure-devices
