Chrystall said the company had traditionally raised institutional money off-shore before tapping smaller local investors.
It already has $92 million committed from institutional investors which includes large pension funds which allocated a certain amount of their money to private equity investment.
Now it was focused on raising up to $150 million from small investors in New Zealand.
"We are targeting $100 million to $150 million - it's very likely we will get into that range."
The new fund is expected to invest into between five and eight companies. The companies will be valued at between $30 million and $200 million.
Chrystall said the type of investments it tended to make included industry aggregations where it merged companies, business turnarounds and growth where it helped companies to expand offshore.
He expected it would take two to three years to fully invest the money raised.
"There is usually a pipeline of investments on the table all the time. We can be working on something for six to nine months."
The fund raising closes on May 31 and has a minimum investment of $100,000.
