Mr Harrell said the brewery had become more than just a place to get a cold ale and rather somewhere to bring the community together.
"We've had really good support and feedback from locals since opening," he said.
"This for us is more than just about drinking a beer, it's a place where people can meet up and have a chance to socialise.
"We've had customers tell us they've met their neighbours here for the first time and actually chatted with them instead of just the usual wave at home, which is really cool."
PhatHouse now distributes more than 12 different beers locally to cafes, bars, restaurants and retailers, it has an online shop and is an approved supplier to Foodstuffs NZ.
Not ones to rest on their keg, the couple extended the brewery earlier this year by installing a pizza oven and the Brewery Bar & Taproom.
If that wasn't enough, the Harrells recently achieved yet another milestone, taking out one of this year's Top Energy Business Development Fund grants worth a cool 30k.
Caroline and Rob said they were delighted with the win and planned to use the money to build on their success by introducing the PhatHouse Brewery Tour.
"This money will help finish the back part of the brewery, which allows for public access in order for us to be able to run the brewery tours," Mr Harrell said.
"We want to create an experience where people can appreciate the whole process of beer making and to understand a bit more about the history.
"It will be a sensory experience of tasting grains, smelling hops and being shown the beer-making process combined with story-telling and product sampling.
"All going well, we should be up and running by the summer season."
Top Energy launched its Business Development Fund in 2014 and is designed to encourage and promote economic growth in the Far North.
Grants of up to $30,000 are awarded twice a year for local business ideas or initiatives that have the potential to grow or diversify the Far North economy.
The money is either awarded in full to a single stand-out idea or in smaller amounts to several initiatives, depending on the number, quality and merit of the applications received.
Top Energy Chief Executive Russell Shaw said the company was focused on supporting business initiatives that economically benefitted the local communities businesses are in.
