Here’s what the locals had to say...

Working with Harrisons was delightful. Even with worldwide shipping disruptions from the events of the past few years, Harrisons delivered! The customer service was excellent - fast communications, expectations exceeded, and ultimately a job completed. Highly recommended!

We investigated 4 companies and chose Harrison’s for their better tech and end to end service, for a complete system and install. Andrew the local agent came around to do a site visit and his solution was simpler and more aesthetically pleasing than others had suggested. All though the system selection and configuration process , Andrew was helpful - He listened to our needs and together we came up with an ideal solution. After a long wait due to demand and supply we finally have a Tesla Powerwall system that does exactly what it we wanted and we are very happy.

Great service and support from Andrew and the team. Fantastic solar system working better than expected. Pricing was spot on and install went smoothly. Highly recommend



I purchased insulation and an i-vent from Andrew for my home. Andrew was super helpful, always thinking how to achieve a win-win deal. It has been 2 years now and I am happy with my purchase. House has never been warmer: this year is the first in my life I didn't need to wear pajamas during winter. The i-vent is used 24/7 to keep the house free of condensation build up. Since installing it there has been no window condensation. Hence five stars.

We have had 18 solar panels installed in 2 stages. Our power bill has shrunk even though it's winter. We are very happy with our investment and the quality service of Harrisons!

Brian Wood


So far the panels have performed better than I expected and this is through winter so cant wait for summer

An Excellent Company offering World Class Products and Services. I have been a client of Harrisons now for several years. I have two of their products, Solar and i-vent. I highly recommend both products and I always recommend people deal with Harrisons. When I was looking for a Solar solution, I wanted the best technology my money could buy. I did my homework and then I was lucky enough to come across Andrew McNabb, who filled in the spaces for me. He confirmed the technology provided by Harrisons was of the highest standard and with me being a "Buy New Zealand" made advocate, I was pleased to see their partnership with a New Zealand company, providing world class Inverters. The purchase and installation were seamless from my side. The technical team who installed this system where friendly and efficient and our relationship has extended to them now becoming my personal Electricians. My second purchase from Harrisons was their i-vent, home ventilation system. I was sick of "crying windows”. Again, I did my homework and I found Harrisons came out on top. I give you my honest assurance my condensation issues were gone the day the i-vent was installed. I have never regretted my decision to go with Harrisons. Months may go past between communications with Andrew McNabb but he immediately remembers me and like the products that he sells, his service is first class. If you are looking for quality products matched with excellent Customer Service, a provider who does not push their client to buy this or buy that, then you will do yourself a favour by dealing with Harrisons. I am waiting for my next opportunity to do business with them because I know I matter and my business matters. Thank you for this opportunity to offer feedback.

Andrew and the team did a good job. Had some delays with installation but were fairly compensated for the inconvenience. We had good communication and were able to get a solution that suited our situation. Thanks... Nice work!

Our old 1920 bungalow, insulated to every inch possible, + grunty woodburner + heatpump + radiators, (+water), resulted in avg monthly bill across calendar year 1 April 2016 to 30 june 2017,of $240 per month.

We're currently tracking in the new house $60 p/month, full utilities incl. gas for hot water. In terms of actual power, about $48 p/mth. Different running costs, eg, septic system, water tank pumps, pool pump + pool heat pump. Overall super happy, and the storage has made a difference.

We'll get through a full winter and see where we're at, but pretty happy so far :)

Really quick and efficient. Franchisee made me feel really comfortable about process

Brian Hulse

Top marks for service. Very prompt replies with full answers and suggestions. No question was too much trouble or too basic. I always got answers and explanations that I could understand. No pushy marketing with different options offered and discussed. Communication was via both email and telephone as well as face to face. One answer to an email query was within half an hour. Excellent service & I am already recommending Harrisons (Andrew in particular) to others.



Great service and product. The I-Vent has dried out our house and has been one of the best things we have done with our renovations.



Dealing with Andrew McNabb was good. He always responded in a timely and efficient manner. Oct 17

Den Ouden


In March we installed a solar system for Mrs Den Ouden in Wanganui. Her main motivation to go solar was to be able to harness the sun's power to generate power to run her home and save money on her power bills for the next 25+ years.

We installed a 3.42 kW system using 12 premium LG 285w Mono X panels with a Solar Edge Inverter with optimizers under each panel for maximum output. She upgraded the inverter to 5kW so in the future it will be easy to add more panels if required and a battery.

Even on a cloudy but light day in September her system produced over 18 kWh, so we are expecting to see some great results over the summer months.

Thanks Andrew for such a smooth and hassle-free service! The ventilation system went in yesterday and we saw a fantastic difference the next morning with NO condensation, just great thank you again!



Firstly let me compliment you on the two installers that arrived this morning. Both Zane & Hayden are a great asset to your business, friendly outgoing guys who took time before they started work to make sure I was aware of what would be done where and most importantly why, and it was all conveyed in a manner I could understand, site was left clean and tidy, small things, I know, but we have had a number of contractors on site in the last 3 months and they could really do with taking a leaf out of your staffs books.

Bev, thank you for juggling your work schedule this week to fit our install in, it really was appreciated.

I would definitely be happy to recommend everyone involved to any prospective clients.

Thank you again.
