The Ministry for the Environment has been surveying all local authorities (regional, territorial and unitary) in New Zealand about their implementation of the RMA since 1996. Nine surveys have been conducted in that period.
A summary of the seven surveys from 1997/1998 to 2007/2008 is presented below. Please note the results from the 1995/1996 and 1996/1997 survey are not included as the data is not comparable.

Data source: 2007/2008 RMA survey data and published survey reports for the periods indicated.
Notes:
The survey question on which this figure was based was amended in 2005/2006 to clarify its intent. Nonetheless, the response from each survey period remains comparable.
The (n = ##) along the x axis refers to the number of local authorities that answered the question on which this analysis is based.

Notes:
'Notified in some way' refers to consent applications that were either notified or limited notified. Before the 2003/2004 survey, limited notified consent applications did not exist.
The percentage of consent applications notified in some way for 2005/2006 and 2007/2008 has been rounded to two decimal places. The remaining surveys have been rounded to a whole per cent.

| Survey period | Percentage of consent applications processed on time (%) |
|---|---|
| 1997/1998 | 78 |
| 1998/1999 | 82 |
| 1999/2000 | 82 |
| 2001/2002 | 82 |
