Napier Mayor Bill Dalton has further improved following a serious stroke last Tuesday night.

"It's still early days, but we are very pleased Bill is now in a stable condition in hospital," said his wife Shirley.

Mrs Dalton said the family wanted to take the opportunity to thank all medical professionals involved in her husband's care.

"We would particularly like to thank all emergency service staff involved for their swift response last Tuesday when Bill suffered a stroke, to the wonderful care he has been receiving in Hawke's Bay Hospital.

We are fortunate he is in such good hands."

Mrs Dalton said the family continues to be heartened by the many messages of love and support.
