KEY POINTS:
A Thai witness who gave evidence against MP Taito Phillip Field will find out this week if his fight to stay in NZ is successful.
Tiler Sunan Siriwan has been in the country for the hearing into allegations of corruption charges against Mr Field.
Mr Siriwan, his wife Aumporn Phanngarm and their 6-year-old son, Henry, have been waiting to hear the outcome of a ministerial intervention into their plight after they were deported in 2006 from Samoa, where he was allegedly working on Mr Field's home.
The family were due to leave Auckland today on a flight to Bangkok but their lawyer, Olinda Woodroffe, said Henry had a serious chest infection.
