Duplicate Magento Store for Another Currency / Domain

We have a Magento store on a .[login to view URL] domain and accepting Australian Dollars. We want the website displayed on a .[login to view URL] domain displaying NZ dollars. We need the pricing in NZ dollars to be automatically updated as the NZ dollar changes against the AUD. We need the new .[login to view URL] site to have the same products as our .[login to view URL] site but with the ability to be able to turn products on and off on each site independently. Please contact me via message to explain how you will achieve this for us and any other things we need to be aware of. We will be looking for someone with the knowledge on this situation and who can help us get this set up quickly.
