FREE Home Insulation to Eligible Home Owners

Too many families in the King Country and central North Island live in cold, damp houses.

Some families struggle to heat their homes or put energy saving measures in place. We aim to do something about it.

Maru is a not-for-profit charitable trust, established in August 2018 by The Lines Company.

We work alongside communities to help combat energy hardship.

Working alongside communities, we are putting in place practical initiatives to help homes become warmer, drier, healthier and ultimately use less energy.

  • You have a Community Services card or SuperGold Combo card OR

Once your home is insulated you may be eligible for a heating grant.

Helping King Country households to save up to $552 a year on power bills.

Te Kūiti Energy Efficiency Expo

In early 2022, Maru partnered with the Ministry of Business Innovation and Employment (MBIE) and Ecobulb Limited to help attendees save up to $552 a year on power. The expo had an excellent turnout from the local community with approximately one-fifth of Te Kūiti homes participating.

  • 440 Te Kūiti homes took part (about 1/5 of TK homes)
  • 211 homes had an energy assessment
  • This led to potential energy savings of up to $162k per year
  • A further 229 homes picked up 5 free Ecobulb LEDs each

This was an awesome initiative for the community and one that will help homes within our network to become more energy efficient.

What people are saying about Maru


Our whare is much warmer thanks to Maru Energy Trust insulating it. I was rapt with the service and phone calls from Maru. Jo was very helpful and worked really hard to help get my whare insulated. My moko stayed with me and said: Nan, something’s not right in my room, it’s warm, it’s usually freezing. It’s warm as Nan!” My mokopuna are loving it.

I’m going to definitely spread the word about the good work Maru is doing.

Highly recommend. Had a heat pump installed in our homestead. The contractors Maru uses are very professional, polite and very helpful in answering questions. They even cleaned up their mess.

We are very pleased with the service we received from Maru Energy Trust after living through a very cold winter and having no proper heating in our whare. Our power bills were unbearable as we used many different heaters to try and keep our son warm. We reached out to our navigator at Taumarunui Community Kokiri Trust and she was able to liaise with Maru Energy. Jo was very helpful and made contact very quickly, the process from there was smooth and not long after we were blessed with a heat pump.

We cannot thank Maru Energy Trust enough for the awesome mahi they do for whānau in our community that are in similar situations.

Much aroha to you all.

Pam, Taumarunui


Was awesome – fast insulation and heat pump installation. No problems in the communications. Thank you so much for making it easy for us.

William & Mania, Te Kūiti
