I'd not in NZ.
But I'm triple vaccinated, had Covid (2020) and in pretty good health.
I'd definitely go wearing a mask, sitting with mate (who I'd see reguarly enough anyway) but otherwise practicing some sensible social distancing.
Omicron ain't suddenly going to disappear after the 'wave' has finished. So not sure risk is going to be much higher during the 'wave', than a few months later when the virus is still very much in the community.
But again they are my individual circumstances, which will be alot different for anyone say older, in poor health, unvaccinated or living with someone in that situation.
