(a) evidence in relation to which Part 3.2 (hearsay evidence) or 3.4 (admissions) applies;

(b) identification evidence;

(c) evidence the reliability of which may be affected by age, ill health (whether physical or mental), injury or the like;

(2) If there is a jury and a party so requests, the judge is to:

(a) warn the jury that the evidence may be unreliable; and

(b) inform the jury of matters that may cause it to be unreliable; and

(c) warn the jury of the need for caution in determining whether to accept the evidence and the weight to be given to it.

(3) The judge need not comply with subsection (2) if there are good reasons for not doing so.

(4) It is not necessary that a particular form of words be used in giving the warning or information.

(5) This section does not affect any other power of the judge to give a warning to, or to inform, the jury.
