There has also been speculation TV3 owner MediaWorks, which also runs Four and operates half the commercial radio market, could float.
And firms that shelved listing plans during 2014 - such as equipment rental firm Hirepool and software developer Wherescape - could have another go.
One public relations agency is understood to be advising about six companies looking to list in 2015.
The 16 new listings of 2014 included 12 main board IPOs, which raised capital, and four compliance listings on the NZAX junior market that did not raise any cash. It was the NZX's biggest year for floats since 2004, when 37 took place.
But analysts say possibly less buoyant market conditions and more discerning investors could result in a downturn in IPOs next year.
"The pipeline is still quite solid and I think there will still be a few opportunities that come to market," said Craigs Investment Partners head of private wealth research Mark Lister.
"Having said that, I think [2015] will be a tougher year in terms of returns for investors. I think we could see people getting a little bit fussier about IPOs over the coming year."
Devon Funds Management principal Paul Glass said he expected 2015 to be quieter on the IPO front than previous years.
"The investment banks just aren't banging the drum in the same way."
However, Glass said historically low interest rates would keep pushing investors towards equities, which could help keep market conditions upbeat. Flurries of IPOs tended to take place during periods of strongly rising markets, as had been the case in the past couple of years.
"Bonds are producing very low yields, bank deposits are at very low levels," Glass said. "In that context I think the equity market remains fairly attractive. The only thing I'd caution there is the equity market itself is quite expensive by historic measures."
Grant Williamson, a director at sharebrokers Hamilton Hindin Greene, said there was scope for the IPO pipeline to keep pumping in 2015 but they were likely to be at the small to medium-sized end of the market.
"I think there will be a number [of floats] in the technology sector provided there's demand for those types of companies.
"A lot will depend on the general state of the market and investor appetite for new listings."
Williamson said it would be positive to see some well-established, privately owned companies going public. "It would be nice to see some manufacturing [firms] coming to market, maybe some export-driven companies. You want to see companies that have a good history behind them and are paying relatively attractive dividends."
Meanwhile, exchange operator NZX is expected to launch its new NXT market during 2015 - targeted at companies in the $10 million to $100 million market capitalisation range.
"The NXT pipeline looks strong in the new year, with a mixture of new companies listing and some others that propose to move across from the NZAX," an NZX spokeswoman said in November.
The NXT, which will eventually replace the NZAX, has less onerous disclosure requirements designed to make it easier and less costly for small, fast-growing companies to list.
Firms previously tipped to be considering listing on the NXT include Auckland's Invivo Wines and technology developers Straker Translations, Fronde and Booktrack.
