"It is not excluded by virtue of revenue sources and while it has some controversy around labour practices and tax policy, it is not cut out on the controversy basis.
"But its ESG score is not high enough to make the portfolio. By comparison Alphabet (Google) has a higher ESG rating and is selected in the portfolio," Berry said.
The company launched a wholesale version of the fund earlier this year after getting a mandate of just under $50 million from Ngai Tahu.
Now it has made a retail version available and is promoting it via online investment platform Sharesies in a bid to tap into a younger market.
Berry said the platform was opening up investing for a whole new generation and it had seen demand from consumers for more socially responsible investment products.
Younger people appeared to be taking a different view on investing, he said.
"They are much more connected with what is going on in the world and are much more connected with environmental issues. Their motivation is not just to make money off investments."
New Zealand has seen a big rise in socially responsible investing in the wake of revelations by the Herald and Radio New Zealand that KiwiSaver funds invested in tobacco and controversial munitions companies.
KiwiSaver providers have since pulled out of those investments, with most taking on an exclusion approach.
Berry said its fund went a step further than that using its extra screening tools and would also change over time to reflect changing beliefs.
"You can't set and forget." If there was a groundswell against something like using palm oil then it would look to exclude companies involved in that.
Berry said it was often asked what cost investing responsibly came with when it came to investment performance.
He said overseas research showed it tended to do at least as well as the market and could do better.
