Administrator – Sustainable Homes & Organisation Support

Do you love creating order, helping people and making busy days run smoothly?

Would you like your administration skills to make a real difference for people and the environment?

We're looking for an organised, proactive Administrator to join our team. This is a varied role that combines administration and customer support for our Sustainable Homes team with administrative support across the wider organisation, including supporting our Executive Team and contributing to organisation-wide projects and initiatives.

Approximately half of your time will support our Sustainable Homes team, with the remainder providing administrative support across Sustainability Trust. If you enjoy variety, building great relationships and helping people succeed, you'll thrive in this role.

About us

Sustainability Trust is a Wellington-based social enterprise working towards a future where everyone can live in a warm, healthy and sustainable home.

Each year we help thousands of households improve their homes through heating, insulation, ventilation, hot water, EV charging and other energy-efficiency solutions. The income generated through these services helps fund community programmes that support people experiencing energy hardship and drive positive environmental change across our region.

We're a collaborative, values-led organisation where people support one another, celebrate different perspectives and work together to create practical solutions for our communities.

About the role

This is a busy and varied role where no two days are quite the same.

You'll help coordinate customer bookings, keep jobs on track, maintain accurate information, support our Executive Team and work closely with colleagues, suppliers and contractors to ensure our services are delivered efficiently and professionally.

You'll be an important part of creating a positive experience for our customers while helping our teams work effectively behind the scenes.

What you'll be doing

You'll:

• Coordinate bookings for home installations.
• Deliver friendly, professional customer service and keep customers informed throughout their journey.
• Maintain accurate information in Salesforce and other systems.
• Support invoicing, reporting and day-to-day administration.
• Work closely with assessors, installers, suppliers and colleagues to keep jobs running smoothly.
• Provide administrative support to our Executive Team.
• Assist with organisation-wide projects, meetings and initiatives.
• Contribute to continuous improvement and support other teams as needed.

About you

You'll thrive in this role if you:

• enjoy helping people and providing excellent customer service
• are organised and able to manage multiple priorities
• have excellent attention to detail
• communicate confidently with a wide range of people
• enjoy solving problems and following things through
• are comfortable using Microsoft Office and learning new systems (Salesforce experience is a bonus)
• value working collaboratively as part of a supportive team
• share our commitment to Te Tiriti o Waitangi, equity, inclusion and environmental sustainability.

Experience in residential heating, insulation or energy-efficiency products isn't essential—we're happy to teach you that.

What we offer

• Full-time role (37.5 hours per week)
• $30 per hour
• Flexible working arrangements by agreement
• Living Wage Accredited employer
• Four weeks annual leave
• A supportive and collaborative workplace where your ideas are valued
• Opportunities to learn and grow across different parts of the organisation
• The chance to contribute to practical climate action while improving the wellbeing of households across our communities
