New Zealand firefighters and a small group of their New York counterparts have walked up the Sky Tower in central Auckland on the 16th anniversary of 9/11.
Before the walk up the Sky Tower, the names of the firefighters who died during 9/11 were read out.
New Zealand firefighters who had lost their lives while on duty were also honoured.
Much of the raw emotion of 9/11 has subsided but it's a day that won't be forgotten, retired New York fire chief Peter Hayden said.
