You can get inflation data here

Series C (for high income families) is probably the most appropriate - covers the spending of the top 10% of HK household
Since B scales started
1993 83.6
1994 92.0
1995 100.6
1996 107.2
1997 113.7
1998 117.3
1999 112.9
2000 108.0
2001 106.3
2002 103.3
2003 100.3
2004 99.6
2005 100.3
2006 102.6
2007 104 (April)
So price level now about the same as it was in 2001/2 or 95/96
Makes sense, a friend came to stay who hadn't been in HK since 1997, his comments were that HK was cheaper than ten years ago.
