Since the reorganization of the INZ website, they no longer give estimated processing times for individual offices, only this.

If you are in a hurry to get to NZ and start working, I suggest you should apply for an Essential Skills work visa, or Work To Residence if the employer is accredited, as well as Residence under SMC, because the work visas get processed much more quickly.
The more points you are claiming, the longer your Residence application will take to be processed, because every piece of evidence has to be verified. With a job offer, you only need 100 points. Just claim what you need, and things will go faster.
