Hi Andrew, there are so may options to engage with designers who can support you. If you are ok with going internationally then try something like fiverr.com where you can find designers from all over the world to work on your brief.

if you want to work closer to home then google NZ freelance designer and you will find people like Unicornfactory.

The key to any engagement is a clear brief, making sure that you’ve confirmed in writing what the requirements are, when they need to be delivered by, style guide and examples of previous work, etc.

Good luck! Vicky
