Gentrack says it will sell its shares at $2.50 each the top end of its indicative range.
The bottom of the range, set for the float of the specialist utilities and airports software company, was $2.
The price means Gentrack will raise the full $99 million it sought, with $36 million of that being new capital which will be used to repay debt.
Existing shareholders will sell 26.3 million shares but retain just over 43 percent of the company.
Gentrack's chairman John Clifford says the price implies a market value of $174.5 million.
Gentrack shares are set to begin trading on the NZX main board on 25 June.
