About the role

Our Finance Operations team incorporates Customer Billing, Credit Control and Accounts Payable & Purchasing. This multi-functional group has the responsibility for providing efficient and cost-effective Billing, Invoicing and Payment support services, to meet the needs of internal and external customers for NZ Post.

We are looking for someone to step in and help keep things running smoothly while one of our team takes on an internal secondment. You will play an important role in supporting NZ Post and our on-account customers through to August 2026.

You will do this by ensuring that all billing information our customers receive is accurate and arrives in a timely manner to enable prompt payment, that all payments received are correctly allocated, and that all customer enquiries are resolved in a timely manner.

In this busy and varied role, you will need to complete all these tasks efficiently and effectively. There will be opportunities to participate in projects, and as part of the wider Group Finance team you will be expected to work collaboratively and, at times, with the flexibility to pick up the work of other roles within the team to achieve team objectives. A vital part of this role is to work closely with the Credit Control team to meet our key objectives and targets.

About You

You will have a passion for delivering exceptional customer service, and you will have mastered the fundamentals of quality in this space, including a good phone manner, excellent attention to detail and a team player approach. If you have experience in accounts receivable that would be a bonus, but not essential.

You’ll Couple This With

• Excellent written and verbal communication skills
• Ability to work to deadlines and under pressure
• A proactive nature and the ability to pick things up with ease
• Comfortable using a variety of systems and processes
• Experience working in a large or complex organisation which has a strong customer relationship component
