Hello @Sharon756 from the North Island of New Zealand.
We all get those emails to reduce our pricing, best to ignore them as they are the same price across all of the world.
I recently had one suggesting I lower my price to $21 per night and I live in Remuera in Auckland which as you know is one of the most expensive areas to live in Auckland.
One can't even stay in a camping ground for that in many places in New Zealand, and definitely can't stay in Remuera Campground out in the rain and cold for that price!
Have a search here in CC using keywords in the searchbox for related topics to learn and seek advice.
There's topics covering basic and important costs to cover including your own time.
It's always a good idea to look up comparable properties in your location to see what they are charging guests.
All the best
