Then there's CBL Insurance, a credit surety and financial risk insurer that's been tipped to carry a float before the end of June.
Let's be clear, from an investor's point of view there's nothing wrong with companies that operate in sectors that may seem a bit dull.
New Zealand's richest man, Graeme Hart (who happens to be Fliway managing director Duncan Hawkesby's father-in-law), has made his most recent billions out of bottle tops, beverage packaging and rubbish bags.
And Warren Buffett, one of the most successful investors to ever walk this earth, has built his empire on the back of insurance firms, whose solid cashflow, provided from customers' premiums, can be used by his Berkshire Hathaway conglomerate for investments.
Some interesting companies have floated on the NZX over the past couple of years, but a number of them have been a let-down for investors since listing.
Orion, ikeGPS and Serko were languishing below their IPO prices yesterday afternoon.
On the other hand, Vista Group and Eroad have been stand-out performers, rising 87 per cent and 40 per cent since their respective listings last August.
Investors will probably welcome the addition of profitable firms with long track records like CBL and Fliway, provided the IPO pricing isn't too steep.
Listings are also expected on NZX's soon-to-launch NXT market, targeted at fast-growing firms valued at up to $100 million.
