The 70-year-old's six grandchildren and immediate family accompanied him at the investiture.
It is not the first time he has been recognised in the Queen's Honours List after being awarded the Companion of the New Zealand Order of Merit for business and philanthropy in 2015.
Sir Paul said he had found his Queen's birthday honour waiting for him in the letterbox back in June.
"But to me, it is more about doing your bit to help the community and others in need of support who are not in a position to help themselves," Sir Paul said at the time.
"I believe that anyone who has been successful in business within a community has a corporate and social responsibility to support and give back to the community."
Sir Paul is the executive chairman of one of the Bay of Plenty's largest land developers, Carrus Corporation, which has developed thousands of sections in Tauranga.
He was also directly involved in bringing the new University of Waikato campus to Tauranga's CBD and donated money for the development of the Adams Centre for High Performance in Mount Maunganui.
But his career highlight has been getting involved in the not-for-profit sector as chairman of Accessible Properties.
Sir Paul and his wife Cheryl are also known for their philanthropic support to many sporting organisations including Bay of Plenty Rugby, Tauranga Golf Club and the Tauranga Rowing Club.
