Butcher said interest rates in New Zealand would have to lift at some point if global interest rates continue to rise, but long-dated interest rates can't rise until the cash rate increases. The "hot money" has left New Zealand in the past year and a half as global interest rates have risen, he said, leaving the market with long-term investors, some of whom have been here for 30 years.
"What's important for LGFA is we are still seeing very strong offshore investor demand for our bonds," he said. "A number of offshore investors want to be in New Zealand for diversification purposes, they have a global fixed-income portfolio, so we are still tapping into that."
Butcher also discussed the financial covenants on its member councils, with all local bodies compliant as at June 30, 2017, and most have "sufficient financial headroom." Auckland Council is a special case and has been exploring options as it has reached its debt cap.
The council has committed to retaining its AA rating, meaning it will need to stay within the financial covenants set by LGFA, Butcher said. It needs more revenue to fund infrastructure, and is still working with central government on off-balance sheet mechanisms such as special purpose vehicles.
Auckland Council can borrow 2.5 times as much as it raises, so can borrow an extra $320 million from the $130 million raised from the regional fuel tax, Butcher said.
"That's not really going to be enough to fix Auckland's transport issues, so this is why there has to be a wider issue of what you can do to fund this infrastructure," he said.
"The first initiative was the housing infrastructure fund in 2016, the latest discussions are around Crown Infrastructure Partners, which has been taking place since July, August 2017. There is a lot of work being done to try and find a solution."
