"As at the time of writing, New Zealand equities trade at a 23 per cent premium to global equities, with low interest rates a key driver. Any change here could see our premium eroded," JB Were said.
In October, for example, a 23 basis point rise in US 10-year Treasury yields saw the equity market weaken by 5.5 per cent, and during November an additional 56 basis point rise in US 10-year Treasury yields saw the New Zealand market weaken a further 1 per cent.
"Accordingly, further increases in bond yields will likely be a headwind for the New Zealand equity market," JB Were said.
At the same time, an obvious by-product of higher bond yields is a more attractive fixed income market, it said.
"Given this, we would not be surprised to see further reductions in New Zealand retail investors' ownership of our market," it said.
"We also expect that the level of foreign ownership of our market could very well fall in 2017 as the global 'hunt for yield' thematic continues to drift out of fashion," it said.
The most significant driver of the observed increase in foreign ownership was a reduction in the proportion of ownership by New Zealand retail investors in favour of offshore managed funds.
JBWere also observed a reduction in ownership by NZ managed funds and an increase in NZ strategic stakes.
This was a reversal from trends observed over recent years, which saw both retail investors' and NZ managed funds' holdings increase.
JBWere said the initial public offer market remained subdued, with just three offers in 2016.
"That said, some further new listings resulting from separations of existing assets shows corporate activity remains alive and well in New Zealand," it said.
New Zealand equity market's capitalisation its at 41 per cent of GDP, the highest level since 2000 - low by world standards but representing an increase from 37 per cent last year, JBWere said.
