text: Keeping business records for seven years.
  Records make it easier to:
  - calculate your income and expenses
  - calculate your GST if you’re GST registered
  - meet your employer obligations if you have staff
  - confirm your accounts.
  Records must be in English or Māori, unless the IRD have given you written authority to keep them in another language.
  You need to keep these records for at least 7 years.
