The New Zealand sharemarket started the week strongly, with key share Telecom adding 4c as it struggles to pull away from a record low earlier in the month.
The positive start also came after China announced it would resume making the yuan more flexible, signalling it was ready to break a 23-month-old peg to the United States dollar.
There was speculation the Chinese move could improve investor appetite for risky assets such as stocks.
