@Carol178, here's one way to find out what people see when they see your listing on Airbnb: Sign out of Airbnb, clear the cookies in your browser, and then run a search for properties in Tauranga for dates you know your property is available. This should let you see what potential guests see.
Remember that your cleaning fee and Airbnb's guest service fee (which is different and higher than the service fee it charges us hosts) will be included in that total amount. These can increase a nightly rate substantially. Our rate is $114 US per night. Once you add the one-time cleaning fee and Airbnb fees, that $114 per night amount suddenly totals around $145.
And as you probably know, the dollar currently is strong against NZ currency ($1.44 NZ dollars to $1 US) so if anything your price should look very inexpensive once converted to US dollars. Though something could be screwy with Airbnb's currency converter algorithms.
Finally, if you have Smart Pricing activated, then it's conceivable that Airbnb is asking that much for some more in-demand dates. But Smart Pricing never raises our price by more than $10 a night or so.
Airbnb's NZ support line is +64 4 4880 888
Hope this helps!
