Thank you OldNGrey!
Loaded the three files from Github and get the following error:

PHP Fatal error: Uncaught Error: Undefined constant "MODULE_PAYMENT_DIRBANKNZ_DESCRIPTION" in /usr/www/users/koineepgvq/zz/includes/modules/payment/dirbanknz.php:35
Stack trace:....

This happens while the payment module list is being constructed and gets to "D"

I don't know why I am battling with such an simple thing. Started to think the problem is deeper because I get the same type of "undefined" error with the Netcash payment module. My shop in now down for some time without a proper payment module...imagine! Shop without a till!
