Some day before, I got a task to change the currency symbol for New Zealand. After some research, i got the solution. Now I am putting the solution here for reference:
I had to change the currency symbol of New Zeland Dollar to NZ$. By default, the currency symbol for New Zeland Dollar is $.
For this, you need to edit lib/Zend/Locale/Data/en_NZ.xml
If you are confuse how I can choose this xml file, So reason behind is that my locale setting is set to English (New Zeland).
You can check you locale setting from
Admin Panel –> System –> Configuration –> GENERAL –> General –> Locale options –> Locale
NOW
– Open lib/Zend/Locale/Data/en_NZ.xml
Find the following code :
<currency type=”NZD”>
<symbol>$</symbol>
</currency>
Just change $ to NZ$, so it will look like
<currency type=”NZD”>
<symbol>NZ$</symbol>
</currency>
upload the file and its almost done.
Now you need to clear you cache which you can do from Admin -> Setting -> Cache Management
