Pregnancy pants? Brands stores NZ or online

Hey looking for recommendations, I’m working in hospitality and I’m needing new pants/ tights for work I normally wear black tights as they are comfy and flexible but I’m bloating heaps and I know within the next month or two I’ll start to really show I don’t mind people knowing as I had to tell work due to severe nausea anyway but looking for something that’s comfy flexible especially around belly and also not see through!!! I tried a few pairs on today Nike adidas puma new balance most stuff my mall has and body cotton on shop and all see through. Advice and recommendations please.
