"This increase from 4.50 per cent p.a. to 5 per cent p.a. represents SBS Bank's commitment to be competitive and support investors looking to grow their money in a term deposit," McLean said.
The small New Zealand-owned bank has taken a competitive stance on attracting deposits this year.
In June it was the first to offer a one year term deposit rate of 4 per cent.
McLean said the last time it offered a 5 per cent rate was in February 2015 and that was on a three-year term deposit.
Term deposit rates have risen much more slowly than mortgage interest rates.
While savers will be pleased to see the rise, the rates still remain well below inflation which came in at 7.2 per cent for the year to September 30.
