The Inland Revenue Department has fixed a website outage which caused stress and frustration for businesses filing their GST returns on deadline today.
Service went down on ird.govt.nz just before lunchtime and went back up after 3pm.
Today is the deadline for businesses to file monthly, bi-monthly and six-monthly GST returns.
IRD Acting Commissioner Martin Smith said an error in system settings had crashed the site.
"We understand this caused inconvenience for a number of customers, particularly those filing GST returns today.
"We acted as quickly as possible to restore services and have taken steps to prevent any further recurrence.
"If customers haven't been able to meet their filing obligations today because the website was down, we'd ask them to file as soon as they are able, but we want to assure them they won't be disadvantaged by something beyond their control."
