Aged care, animal welfare, the arts, child health and welfare, conservation, education, the environment, families, hospitals, medical research, mental health and rescue helicopters all benefited from the largesse of this group.
And, of course, it's these Rich Listers' family members and other halves who frequently become involved with charity work.
Tireless fundraiser Dame Rosie Horton was recently honoured for her services to philanthropy. Roxane Horton chaired the Friends of the Liggins Institute committee for several years. Graeme Hart's daughter, Gretchen Hawkesby, currently heads the Friends of Starship. Far from being ladies who lunch, these are savvy women who use their networks to embark on fundraising projects and organise charity events for worthy causes.
Years ago I attended a fundraising auction for Counties Manukau's Kidz First hospital where guests were enthusiastically bidding for items to raise funds for this new children's hospital. Often they'd pay well over the face value of the goods or services on offer because the money was going to such a good cause.
Although not on the Rich List, the guests were, broadly speaking, well-heeled - and many of these people were benefiting the New Zealand health system in three separate ways.
Firstly, they paid taxes which funded public healthcare.
Secondly, the majority of them would likely have opted to pay for private healthcare (either directly or through insurance) for themselves and their families thus easing the burden on the public system.
And, thirdly, this same group of people regularly purchased tables at or made significant donations to fundraising events such as the Kidz First one.
The fact that certain sectors of society are effectively contributing financially on three different levels is not an oft reported fact. It doesn't sit well with the belief peddled by those who subscribe to the so called 'politics of envy' that the wealthy are greedy, selfish and irresponsible.
Yet surely without those folk from the Rich List and other fiscally fortunate groups New Zealand would be poorer in more ways than one.
