Air New Zealand has made further cuts to some regional flights in what one mayor calls "disappointing news". The national carrier last announced reductions earlier this month, citing ongoing high costs for jet fuel. The conflict in the Middle East is affecting fuel supplies globally.  Nelson mayor Nick Smith said today a further 23 flights were being cut between his city and Auckland, 32 to and from Wellington, and 15 to and from Christchurch. The cut flights are between June 29 and July 26. "This is the third time Nelson flights to and from Auckland, Wellington and Christchurch have been axed temporarily since the war in Iran started and brings the total number of flights lost to 266 or about 12,000 seats," Smith said.  He said the latest cuts reduced seat capacity for Auckland by 8.7%, Christchurch by 10.3% and Wellington by 15.2% over the four weeks.…
