He said the recent market turmoil - driven by a Chinese sharemarket rout and fears about the outlook for global growth - would have an impact on CBL's final pricing.
The Australian newspaper reported fund managers were expected to lobby for the shares to be priced at the lower end of the range due to "choppy market conditions".
Rickey Ward, New Zealand equity manager at JBWere, said the poor performance of many recent sharemarket listings meant fund managers were "putting the ruler" over new offers more carefully than they might have in the past.
"You could have floated anything, effectively, a couple of years back," Ward said.
"Fund managers are scrutinising the underlying earnings, and multiples you pay for that, a hell of a lot more today than they ever have."
CBL managing director Peter Harris said on Monday that the volatile environment could have a small impact on the final pricing.
"But we're talking with investors who see well through this and are looking at the fundamentals and the track record of the company."
Existing shareholders are expected to retain a 60 to 63 per cent stake.
