Your domestic flight within NZ requires check-in at least 30 minutes before departure. For international flights, a typical minimum lead time is 90 minutes.
Qantas says (assuming economy class):
The Auckland international terminal isn't anywhere near the size of LAX or DFW. Wait times for security are usually not very long. However, there is an extra secondary security screening for flights departing to the USA. This usually isn't very long either, but I would allow at least 2 hours for your NZ-Hawaii leg.

Can confirm, I flew from Sydney to Christchurch last night (Jetstar) and have done trans-Tasman and domestic flights in both countries.
It's generally airline dependent, and sometimes depends on plane-size for boarding times, but in terms of checkin, most international flights will open for check-in 3 hours before, and close 90 minutes before the flight.
My boarding time last night was 35 minutes before departure. Another flight leaving later had an earlier boarding time, but was on an A-380 - so they need more time to load more people, I presume.
Again, even with the same airline, it can differ with airports.
So let's look at Jetstar, for example:
Jetstar timelines for domestic flights
Jetstar timelines for international flights
where checkin closes 45-60 minutes beforehand.
